This is going to be a two part (possibly three) part series about Earth.
The time it takes for one Earth day (just pretend your martians, I know you know this) is actually 23 hours 57 minutes, but we round it up (I never knew that, did you!?)
One year is 365 days and a quarter, so every four years, so we have a leap year to make up for the quarters.
Basic interesting facts
Picture of Earth from NASA. |
- The Earth has one moon
- Someday the moon will fly off into deep space as the gravitational pull of Earth will loose it's grip.
- The Earth's surface is two thirds water, but compared with the whole inside of the Earth it only covers a measly 0.0002 of Earth's mass.
- Earth is not the only planet that had or has water, Mars used to have water too, but I'll explain that when I get to the Mars section.
