“My very educated mother just served us nine pies.” Ah, good times, right? I hope you don’t live with apes. I also hope you’ve heard of The Big Bang Theory, (not the show, geeks). Here are some facts about planets in our solar system you had no idea about. (Pluto is a planet, get over it already). Also, the SI units used here are all standard, taking EARTH into consideration.
1. MercuryThis one is the closest to sun (57.91 million km away from sun). A year on Mercury is 88 days long. But still, Mercury is only the second hottest planet. It is closest to sun, due to which it spins slowly. Thus there is no atmosphere to trap heat. When Mercury was formed, it had Iron Rivers. Over the time, these solidified, and so these rivers appear like wrinkles. Guess the smallest planet( diameter 4,879 km )is also the oldest, am I right? Mercury also has molten core. This is weird because, being a small planet it is supposed to have a solidified core. It has a lot to do with magnetization, and magnetic fields which shall be covered some other time.
2. Venus108.2 million km away from the sun. A year on Venus takes 225 Earth days. Once upon a time a wayward asteroid hit Venus so hard, it got traumatized and Venus changed its path. So it started spinning, and revolving in the opposite direction. Who’s the second brightest kid in the lot? Venus it is. It is so bright, you can actually see it even during the day, provided a clear sky. It is also the hottest. And is considered a sister of Earth, they have approximately same diameter (12,104 km.)
3. Earth149.6 million km away from sun. It is also the densest planet on Earth. It has one moon, and it is the only planet not named after a god. Most of all the facts, these are the most common ones. But here you are going to be shook. Earth is gradually slowing down. No seriously, Earth is slowing down by 17 milliseconds per hundred years. Why it should matter to us? 1. Because we live here. 2. Because this explains the change in climate over the years. For instance, rains during winter. Snow in Sahara. So much more can be explained.
4. Mars227.9 million km away from the sun. 1 year on Mars is 687 days on Earth. Also Mars being the enthusiastic kid popped some zits whose remains orbited the Earth’s atmosphere for a long time, after which, they fell onto Earth. Due to which studies upon Mars had already started even before having access to modern technology. Hypothetically, one day Mars will have its own ring. Moon named Phobos belongs to Mars. Phobos will break into multiple pieces and the remains will surround Mars for quite a long time (100 million years).
5. Jupiter778.5 million km Away from the sun. It is the fourth brightest object in the solar system. It has a red spot on it which most of us know about. This red spot is actually a really huge storm, huge enough to accommodate 3 earths in it. It has 4,300 days in a year. It also has the greatest gravitational pull in all of solar system. Due to the rapid revolution it flattens out at the top, giving it an oblate shape. Jupiter which is primarily made of hydrogen gas, below the atmosphere lays concentrated hydrogen, ice, liquid metallic hydrogen. Ganymede is the largest moon in the solar system which belongs to Jupiter.
6. Saturn1.429 billion km away from sun.11000 days on Saturn make a whole year. Largest planet in the solar system, hence it can be seen with a naked eye too. Also it is the fifth brightest object in the solar system. Saturn is also the flattest planet, and has the most prominent rings. The outer parts of the rings are mostly ammonia ice, and inner parts are mostly water ice. Saturn has 107 moons and more moonlets. The yellow and gold bands that you see on Saturn’s surface are due to heat that rises from the interiors that combine with winds that flow 500 miles per second.
7. Uranus2.871 billion km away from sun. 30687 days make a whole year on Uranus. What is weird is that Uranus is shifted at 90 degrees due to which it appears to roll on its side. Scientists assume that this is due to two or more small but effective collisions tilted the planet. Hence giving it the retrograde motion. It has two very dark and very thin rings around it, most probably caused due to one of the moon breaking up in an impact. The gases are so poisonous and concentrated that no one can explore Uranus (pun intended).
8. Neptune4.498 billion km away from the sun, 60,200 days make a year. It spins very rapidly on its axis. Neptune has a lovely blue color that is caused by absorption of red light due to methane. It has a small collection of unique rings. It also has unique moons, one of which is extremely cold that spews frozen nitrogen. This is weird because being so far away from sun; this planet has an exceptional gravitational pull, so much so it turned gas into a moon called Triton.
9. Pluto (dwarf)3.67 billion miles away from the sun. 90,500 days make a whole year. Pluto is smaller than our moon itself, but it is the biggest dwarf planet out of a hundreds of them. Pluto is one third water, which is thrice the amount of water on earth. The remaining two thirds is mostly rocks and land. Pluto’s orbit is inclined at 17˚ which makes it periodically closer to sun than Neptune itself. When Pluto’s elliptical orbit brings it closer to the sun it periodically makes an atmosphere when the ice thaws (semi liquid state), which primarily consists of nitrogen. Methane is also released which dissipates into hydrogen molecules, forming a black layer.
