How many suns does earth have

Earth has only one sun, which is the star we orbit around. However, the universe is full of stars, with approximately 200 billion stars in our Milky Way galaxy alone1. If we consider all stars with planets as "suns," there would be an estimated 20 sextillion suns2.

Earth''s revolution and rotation around the Sun, explained

NARRATOR: Earth experiences two different motions, rotation and revolution. Earth spins on its axis, and it takes one day to do so. In one day Earth makes one rotation on its axis. Earth also travels on an elliptical orbit around the Sun. And it takes one year to make a complete trip. In one year Earth makes one revolution around the Sun.

Moon Facts

The resulting debris from both Earth and the impactor accumulated to form our natural satellite 239,000 miles (384,000 kilometers) away. The newly formed Moon was in a molten state, but within about 100 million years, most of the global "magma ocean" had crystallized, with less-dense rocks floating upward and eventually forming the lunar crust.

How big is the sun? Facts & size comparison

1.5 million Venus-sized planets could fit inside the Sun. Earth: The Sun is 109 times larger than Earth. We know that the sun has a diameter of 864,000 miles. Multiplying this number by pi will give the sun''s circumference: 2,713,406 miles. Another way to appreciate the size of the Sun is by calculating the time it would take to travel
