The Milky Way
The Milky Way is our galaxy: it is an immense group of stars held together by the force of gravity; it has the shape of a flattened disk, with a bright core in the center, where the star density is very high, and spiral arms around it. Around the core, there is a spheroidal halo, which extends outside the galactic planet. At this point, it could be useful to introduce the parsec, equivalent to 3,26 light years, to measure the dimensions of our galaxy. So, our Milky Way has a diameter of around 30000 parsec, which is equivalent to 100000 light years. So, if we were back on the Millennium Falcon again and had to cross the Milky Way from one side to the other traveling at the speed of light, the fastest thing there is, it would still take us 100000 years to cross it all.
A galaxy
A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems. our solar system is a small part of the Milky Way Galaxy. The Andromeda galaxy is the nearest galaxy to the Milky Way. It is at a distance of 2.5 million light years from the Milky Way galaxy.A galaxy is made of billions of stars as well as their solar systems
The Romans named the planets after their gods.
Mercury
Mercury is closer to the Sun it is the second hottest planet. In a year its Surface is 88 days .it's the smallest planet, It's a little bigger than Earth's Moon. Fastest Planet and Tough Place for Life. Mercury is the planet that orbits the closest to the Sun. Mercury Nothing orbits faster than it mercury is the smallest planet with Rough Surface. Humans can't breathe there, it is the second hottest planet. Mercury is moonless and Ringless, Small World. Mercury is the smallest planet in our solar system only slightly larger than Earth's Moon no one is smaller than it no one is smaller than it. Messenger of the Gods is what Mercury means the Romans gave it the name Cause, Messenger of the Gods.59 Earth days equal one day on it. The surface is made of stone covered and craters of oxygen sodium hydrogen helium and potassium make up the exosphere. It is the first planet from the sun.
facts about Mercury
⦁ Mercury is the first planet from Sun ۔
⦁ Mercury is an average distance of 48 million miles (77 million km) from Earth. )140.2 million km
⦁ Light takes 7 minutes and 36.3974 seconds to travel from Mercury and arrive to us.
⦁ At its average distance of 36 million miles, light takes 3.21 minutes to reach Mercury from Earth.
Venus
It is the third brightest object in our solar system and we see it to the naked eye from the planet of Earth when humans look up in the sky It is Venus.
Venus is the hottest planet in our solar system but the second planet from the sun is the brightest planet in our solar system. Its thick atmosphere is full of greenhouse gas carbon dioxide, and it has clouds of sulfuric acid. The atmosphere traps heat, making it feel like a furnace on the surface. It's so hot on Venus, the metal lead would melt. Temperature is 900 Degrees yeah that's fairing height the hottest planet in the solar system that's right the sun sets in its East and comes up in its West due to retrograde rotation I spin backwards. It has volcanoes mountains and some big lava planes. Venus after the goddess of love the Romans gave it the name due to its brightness. A day on Venus lasts 243 Earth Days.
facts about Venus.
⦁ light years does it take to get to Venus from Earth at its average distance of 42.2 million miles, light takes 3 minutes 46 seconds to reach Earth from Venus.
⦁ light yellowish
⦁ Venus is a similar size to Earth and appears to have similar.
Earth
Earth Blue planet where we live. The third planet from the Sun Earth is the only planet with Organic life so take care of it. Earth is the only planet with Organic life with 8.7 million species .atmosphere is 78 percent nitrogen another 21% of it is oxygen another small percentage of other elements without the atmosphere around we would be frozen, It takes 365 days to orbit and the sun's rotation is 24 hours makes one day. The largest valley in the world is the rift valley. The Pacific Ocean is the largest and deepest ocean in the world. Antarctica is the largest desert on earth, almost twice the size of the Sahara Desert. The highest mountain in the world is Mount Everest. Only a planet's gravity's pulling us down as fast as 9.8 meters a second, The Earth has three main climate zones: tropical, temperate, and polar. The climate region near the equator with warm air masses is known as tropical. Earth was about 4.5 billion years ago. Distance from Earth to the sun is about 93 million miles (150 million kilometers),
The Earth takes a year, and 365 days, to travel its orbit, and its average distance from the Sun is 150 million kilometers, which is the measured unit of distance in the Solar System.
the average distance from Earth - Sun is equal to about 8 light minutes this means that sunlight takes 8 minutes to arrive on Earth.
Apollo astronauts covered the distance of nearly 400 thousand kilometers that separate the Moon and Earth.
Mars
it is red in color and the fourth planet from the sun the highest mountain in our solar system. Mars is named after the Roman god of war Mars. has seasons, polar ice caps, volcanoes, canyons, and weather. The highest mountain and volcano in the Solar System is on the planet Mars. It is called Olympus Mons and is 16 miles (24 kilometers) high. Mars has 2 moons called Deimos and Phobos. Mars is smaller than Earth with a diameter of 4217 miles. It has a very thin atmosphere made of carbon dioxide, nitrogen, and argon. Temperatures on Mars average about -81 degrees F-220 degrees.
⦁ Mars is not suited to human visitors.
⦁ The distance of Mars from Earth is currently 302,949,675 kilometers,
⦁ Mars is famous for its seasons, polar ice caps, volcanoes, canyons, and weather.
Jupiter
The fourth brightest object in the solar system and 5th planet in our solar system is the biggest planet in our Solar System. It was named after the king of the Roman gods. Jupiter's iconic Great Red Spot. Jupiter also has several rings, but unlike the famous rings of Saturn, Jupiter's rings are very faint and made of dust, not ice. It has 80 moons and A day on Jupiter is super fast and a year on Jupiter is the same as 11.8 Earth years. It is a gas giant and doesn't have a solid surface, it has a solid inner core about the size of Earth. According to Roman mythology, Saturn is the father of Jupiter. The oldest planet f the solar system is Jupiter formed less than 3 million years after the birth of the solar system, making it the eldest planet.
⦁ Jupiter's environment is probably not conducive to life it probably does not have a solid surface
⦁ The gas it is made up of would be toxic for humans so there is no life.
⦁ Jupiter's distance from the Earth is 365 million miles (588 million kilometers)
⦁ Jupiter's planet's distance from the sun is 484 million miles (778 million kilometers)
⦁ The color of Jupiter is white, orange, brown, and red,
Saturn
Saturn is the sixth planet from our Sun (a star) and orbits at a distance of about 886 million miles (1.4 billion kilometers) from the Sun. Earth is about 1.2 billion km (746 million miles). Saturn also known as Ringed Plane, it is a giant gas planet, Saturn planet color yellowish-brown. Saturn's high-altitude clouds are made of colorless ammonia ice. Saturn is unique among the planets,Its have beautiful rings. Saturn has 124 moons. Saturn's largest moon Titan is bigger than both Mercury and Pluto. Saturn was named after the Roman god of agriculture also in Roman mythology. He was described as a god of time, generation, dissolution, abundance, wealth, agriculture, periodic renewal, and liberation.
In astrology, Saturn is often called the god of karma or justice. It is associated with ethics, justice, career, achievements in life, virtues, and values.
Uranus
Uranus is the seventh planet from the Sun which looks blue in color. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus is four times wider than Earth. the only planet whose equator is nearly at a right angle to its orbit. Uranus has a set of 13 rings. It has a thick atmosphere made of methane, hydrogen, and helium. Uranus is the only planet that spins on its side. Uranus spins in the opposite direction as Earth. It is the second-least dense planet. Uranus has 27 moons. Uranus and Neptune are rich in water. William Herschel first discovered Uranus in 1781. A new study has found that “diamond rain” may be more common on ice-giant planets like Neptune and Uranus.
Neptune.
Neptune eighth planet from the Sun. Neptune is the final planet in the Solar System. Neptune is the giant planet and the densest planet. It is called a blue planet, It was named after the Roman god of the sea. Neptune is very similar to Uranus. Neptune is the windiest planet in our solar system it dark planet, Neptune is cold, and it has six rings, but they're very hard to see, the densest giant planet. It is 17 times the mass of Earth. The blue-green color of the planet is due to the presence of methane in the atmosphere. Neptune is still very cold, of course – usually around -214℃.
The Black Hole
Sagittarius A *
Scientists have captured the first image of the monster black hole lurking at the heart of our galaxy. Sgr A* is 4 million times greater than that of our Sun.
Our galaxy's black hole, in numbers
27,000 light-years: Sagittarius A*'s distance from our Solar System
4 million solar masses: Sgr A*'s mass
6 million kilometers: the radius of Sgr A*'s event horizon
240 million years: the time it takes for the Milky Way to make one full lap around the black hole
The black hole, known as Sagittarius A* or Sgr A*, lies 27,000 light-years from the Sun.
Black Hole
The Black Hole made around 25 orbits around the center of our Milky Way, traveling at 215 km/s it is good that the Sun is not in the center of the Galaxy, because in it there is a supermassive black hole: Sagittarius A *, a monster with a mass equal to about 4.3 million times the solar mass and an immense gravitational field, such that even light is not able to escape. Sagittarius is the supermassive black hole at the Galactic Center of the Milky Way. The Sagittarius dwarf galaxy has been orbiting the Milky Way for billions of years. As its orbit around the 10 000 more massive Milky Way gradually tightened, it started colliding with our galaxy's disc. The most well-understood collision is that between the Milky Way and the Sagittarius Dwarf Galaxy.
Sun
During the 1600s, Galileo Galilei, the famous Italian astronomer, was one of the first people,
during the modern age, to have some doubts about the geocentric model of the universe:
thanks to telescopic observations, he was able to demonstrate our Earth is not at the rotation
center of planets and the Sun, but really it is the Sun itself. Moreover, observing planet Jupiter, he discovered that the giant planet is the rotation center for its moons. So,
Galileo became aware that the center of the Solar System was the Sun.
light years
A light year is the distance covered by light in a year in the vacuum and is equal to about 10000 billion kilometers.
Asteroids
Asteroids are those small rocky bodies, whose dimensions span from a few kilometers to a few hundred kilometers. They are so small that they aren’t visible through the unaided eye, but only through telescopes
It is thought that our universe contains around 200 billion galaxies, everyone with 200 billion stars. imagine that, with satellites, space probes, and telescopes, we have explored so far only a very little percentage of the Universe.
