Our Solar System
The closest galaxy we know in space is the Canis Major Dwarf Galaxy but we currently do not have the technology to go past our own galaxy but we can expect space travel in the near future the discovery of the Canis Major Dwarf Galaxy was in 2002 after scientists were examining filaments of stars, gas, and dust which was later found to be parts of the Canis Major Galaxy due to it being pulled apart by the Milky Way Galaxies gravitational pull. It is about 25,000 light years away from the sun.
​
Our galaxy consists of a variety of planets each with its different traits here’s all information about the planets and more in the Milky Way Galaxy
Mercury
Mercury is the closest planet to the sun, which means that it is extremely hot. The temperature on Mercury is 800 degrees Fahrenheit or 430 degrees Celsius and on the dark side of Mercury it is -300 degrees Fahrenheit because Mercury has almost no atmosphere, it can not hold any heat. It has a diameter of 3,032.29 miles or 4,880 kilometers. Mercury doesn't have too much terrain, it only has craters from asteroids that crashed on to it and lots of flat land.
Venus
Venus is the second planet from the sun. Venus's temperature is 880 degrees Fahrenheit 471 or degrees Celsius. Venus is hotter than Mercury because the atmosphere acts as a greenhouse and other gases. Venus's diameter is 7,520.8 miles or 12,104 kilometers. Venus's terrain is very deadly, it has many mountains and volcanoes and a lot of its surface is covered in lava. This place is not recommended to visit.
earth
Earth is the third planet from the sun. It is also the only planet that has life, for all we know. It's highest temperatures are 134°F or 56.7°C, and this was recorded in 1913. The lowest temperature is -89°C or -128°F in 1983. Earth's diameter is 7,917.5 miles or 12,742 km. On earth there are lots of terrains like mountains, plains, forests, deserts, rivers, and oceans.
Mars
Mars: Mars is the fourth planet from earth. The interesting thing about Mars is that scientists believe that Mars contains life because at the top of mars, there is ice which means water. If a planet has water, then it can most likely sustain life. The highest temperature on Mars is 70°F or 20°C. The ice caps on the poles of Mars are -225°F or -153°C. Mars's diameter is 4,212.3 mi or 6,779 km. Mars is mostly made up of volcanic basalt rock, and also Mars's atmosphere is a lot thinner than earth's so you can not breath Mars's air because it is mostly made out of carbon dioxide. The terrain on Mars is made up of craters, canyons, volcanos, and the rest of the planet is made up of red dust.
gas Giants
The gas giants are the biggest planets in our solar systems. They are called gas giants because they are not solid which means that we cannot land on them. If we were to launch something into a gas giant it would go straight through it, and if they were solid and we were too land on them, the gravity would pull up down extremely hard because of the size of the planet. On Jupiter there is a big red dot on it for more than a 150, and that big red dot is a huge storm. Saturn and Uranus are the only gas giants that have rings around them. The rings are made out of watery ice, particles, and other types of rocky material.
What about Pluto?
Then there was a discovery in 1930, and the planet we know as Pluto. In August 2006, Pluto was officially announced as a dwarf planet. Pluto was announced as a dwarf planet because it did not fit the checklist of being a planet. In order for anything to be considered as a planet, there are rules and these are the rules, it must be orbiting the sun, it must be a sphere, and it has to clear the neighborhood. The last reason, it must clear the neighborhood, is why Pluto is not a planet anymore. Clearing the neighborhood means that the planet has no nearby objects with the exception of it’s satellites which are its moons.
