How small is the human being in the universe?

Earth has nearly 8 billion people, each of us is just a pointless little dot. Now look wide and see how small we are in the universe.

Sometimes you think for yourself, we are the strongest on this earth. We own our earth and our living space. But have you ever thought in this vast vast universe, how is our earth?

This is our Earth

What science now knows about the size of the universe shows us the vast and vast realm of the universe - but it is still a very small, very small point in trillions of universes. .

The diameter of the Sun is about 100 times the diameter of the Earth.

The Earth is too small for stars in the solar system

The largest star we know is VY Canis Majoris, about 2,000 times the size of the Sun, with a diameter of about 1.8 billion miles, much larger than the Sun's diameter of 860,000 miles.

From the perspective of human size, if a passenger plane flies at nearly 900 km / h, it takes about 1,100 years to fly around that star.

Too small for the Sun.

It is estimated that there are about 100 billion to 300 billion planets in our galaxy. According to Cornell University's "Ask cosmologist" website, cosmologist Karen Master said: ' Through 3D map searching in the universe, we know there are more than 100,000 galaxies'. But the total number of unknown galaxies is about 200 million.

Gayle Laakmann McDowell, software engineer working for Microsoft, Google and Apple will help us understand how big a billion ' is. She used about 100 billion galaxies in the universe to compare.

The Milky Way, a medium-sized galaxy, is about 100,000 light-years across. So a spaceship takes 200,000 years to travel, both back and forth at the speed of light.
