Gravity
By Sharon Fabian |
|
1 Gravity is not just a force on planet Earth. Each planet has its own gravity, and each planet's gravity is different. Our moon has gravity too. So do the moons that circle other planets. The sun has gravity (lots of it). So do all of the other stars. In fact, everything has some gravity, but only really big things like planets, moons, and stars, have enough gravity to be measured.| Earth - 100 lbs | |
| Moon - 17 lbs | |
| Mercury - 38 lbs | |
| Jupiter - 236 lbs | |
| Pluto - 7 lbs | |
| the sun - 2407 lbs | |
| a white dwarf - 130,000,000 lbs | |
| a neutron star - 14,000,000,000,000 lbs | |
| in a spaceship far out in space - 0 lbs |
