How many Earths could fit in the universe?

By dividing the two volumes we get a factor of 3.2⋅1059, or written as decimal number: The observable comoving volume of the universe is about 320,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000-times the volume of Earth.

Is Star bigger than the Earth?

Yes! In fact, most stars are bigger than the Earth. The diagram below compares the size of our sun with the sizes of the other planets in our solar system. The sun is much bigger than the Earth, and it isn’t even a particularly large star.

Where is a shooting star?

A “falling star” or a “shooting star” has nothing at all to do with a star! These amazing streaks of light you can sometimes see in the night sky are caused by tiny bits of dust and rock called meteoroids falling into the Earth’s atmosphere and burning up.

What is the most likely cause of a meteor shower?

The rocky debris, consisting of mostly sand-size particles, continues in an elongated orbit around the Sun close to that of its parent comet. When the earth intersects this orbit in its annual trip, it can run into this debris, which burns up on entry into the earth’s atmosphere, producing a visible shower of meteors.

What would happen if an asteroid hit the ocean?

Asteroids passing by Earth (as in this illustration) pose an impact hazard that researchers are trying to better understand. When an asteroid hits the ocean, it’s more likely to produce storm-surge-sized waves than giant walls of watery death.
