Gravity isn't just the rule for orbits around the sun or apples falling from trees.
It orbits the Earth every 90 minutes, traveling at 8 km/s,
It orbits the Earth every 90 minutes traveling at 8 km per second, and has hosted over 3000 research investigations from 108 countries.
The moon orbits the earth once per month, which means the moon is on the sun's side of the earth every month.

You see orbits every day: when you throw a ball it makes a tiny little orbit.

Niels Bohr says, "I can explain the different sizes of the orbits of the electrons in the atoms." Louis de Broglie says, "It's even better if you imagine that those electrons are waves rather than particles." Werner Heisenberg says, "I can invent a theory using matrices that explains exactly what's going on." Max Born and Pascal Jordan say, "We can improve the mathematics of Heisenberg's theory to make it more general." Erwin Schrödinger comes along and says, "We can replace the matrices by waves." And then Max Born comes again and says, "Actually, these are useful for predicting probabilities." Wolfgang Pauli says there's something called spin,

This matter can become incredibly hot, as close orbits can speed this matter up to half the speed of light, and
These fireballs were traveling along nearly identical orbits between Earth and the asteroid belt.

So while the Earth orbits around the Sun in a full year, it spins around 365.25 times.

We think of the moon as orbiting the earth, following a spiraling trajectory as the earth itself orbits the sun.
