We have 8 planets and 5 dwarf planets in our solar system. Jupiter is by far the biggest planet. The red little storm on Jupiter is 4 times bigger than Earth. Mercury comes in as smallest. It's around 3 times smaller than Earth. The smallest isn't always the closest to the sun. For instance, Mars is smaller than Earth.

            Below is a list of all the planets and their quality's.

Name	Diameter	Distance from the Sun	Orbit Period
Mercury	4,879 km	57,909,227 km (0.39 AU)	88 day
Venus	12,104 km	108,209,475 km (0.73 AU)	225 days
Earth	12,742 km	149,598,262 km (1 AU)	365.26 days
Mars	6,779 km	227,943,824 km (1.38 AU)	1.9 years
Jupiter	139,822 km	778,340,821 km (5.20 AU)	11.9 years
Saturn	116,464 km	1,426,666,422 km (9.58 AU)	29.5 years
Uranus	50,724 km	2,870,658,186 km (19.22 AU)	84.0 years
Neptune	49,244 km	4,498,396,441 km (30.10 AU)	164.8 years

Black Holes

           Black Holes - Black holes are by far the strangest thing that we have ever encountered in our space, science history. Black holes suck up anything that comes in their path, and if a person ever happens to get close enough to enter it, they will be killed. Not just because it sucks you in; it’s because the black hole’s gravity is so immense that you would be pulled apart and smashed flat. If we ever get the chance to see/know what is on the other side, it would probably be the most amazing thing that we have ever seen. All the light/energy the black hole has ever captured is trapped in there and remains inside. Some people think that if you were able to enter into a black hole, it would show you images from the past.  It is an amazing thought that might be able to see dinosaurs. But all of that is very unlikely, it would take us millions of light years just to reach the closest black hole.

The Moon

            The moon is one of the biggest factors that we need for life. Back when the earth was still forming we captured our over sized moon. When we captured the moon, it was a lot closer to earth than it is now. As you may know the the moon is the cause for ocean waves. The moon’s gravity pulls on the ocean, that is why we have waves. But back when the moon was closer it’s gravity was stronger on the earth. Right now we measure the waves by feet, if the moon was still that close to earth we would measure it in miles. It would be like huge tsunamis every time their was a wave. When the moon was that close it was actually a good thing, it helped mix in all of the chemicals and minerals to help create life. You may think that the moon is a dead rock, but in some recent research we have seen the moon have some explosions. In order to have explosions you need heat energy, and a planet is alive if it has energy.
