    There were nine until Pluto was downgraded to a dwarf planet. We miss you, buddy.

    Venus

    Despite being a total planetary diva, no one put a ring on Venus. But guess what? Someone really liked the gas planets in our solar system, because they ALL have rings!

    ISN'T IT BEAUTIFUL? Like Jupiter and Saturn, Uranus is mainly composed of hydrogen and helium.

    Venus

    Even though it's farther from the sun than Mercury, Venus is the hottest planet in our solar system because its atmosphere is better at trapping and retaining heat. In fact, it's so hot on Venus that you can melt lead on the surface.

    Asteroid Belt

    Though yes, the outer planets are larger, gaseous, and farther away from the sun than the inner planets, the physical entity that separates them is an asteroid belt between Jupiter and Mars.

    There are four planets each in the outer AND inner solar systems. They would make great rival polo teams.

    Neptune

    Neptune is the farthest planet from the sun, and it takes about 165 years for this blue giant to make a full rotation around it. Basically, we're seeing Neptune the same way people in the 1850s saw it. Crazy, huh?

    With its abundance of carbon dioxide, Venus might be super gassy, but like its fellow inner planets Mercury, Earth, and Mars, it has a solid crust.

    Yup, this windy planet is the baby! Not by much, though. Neptune's diameter is 49,244 km and Uranus, which is only slightly bigger, has a diameter of 50,724 km.

    That's because Jupiter is HUGE and has a strong gravitational pull. Just think of Jupiter being a very enthusiastic hugger!

    True

    Isn't that wild? Think about how big Jupiter and Saturn are. Those gas giants and every single other planet can fit between our planet and our moon, and the moon STILL has such an effect on our tides while shining so bright and beautifully in our sky.

    And some of Saturn's rings are thousands of miles wide. It would take over a week to drive over some of them. We are so, so tiny.

    Mars has two little moon sons called Phobos and Deimos, named after the Greek gods of fear and panic respectively. They look kind of weird for moons and are shaped like potatoes. #same.

    Venus takes 5,832 hours to make a full rotation on its axis, BACKWARDS, might I add (relative to the other planets). That's about 243 Earth days. Ma'am.

    There are several theories as to why. One theory is that these planets were hit by large objects that changed their rotation early on.

    Mercury and Venus

    The two planets closest to the sun don't have any moons. Why? Well...because they're close to the sun. With the sun's gravitational pull, the margin for a stable moon orbit is very narrow. Chances are high that they would be tractor-beamed into the sun and destroyed. ¯\_(ツ)_/¯
