Who better to explain Earth on Earth Day than Neil deGrasse Tyson?

The astrophysicist, cosmologist, author, TV show host and science communicator took to Twitter today to share some facts about this green and blue planet in honor of Earth Day.

Tyson began his Earth Day tweets by telling his audience that he was "feelin' Earthy today." Then, he began to post some facts not just about Earth Day itself, but also about Earth.

Warning: these tweets will make you feel small, very small, because as Tyson points out, the Earth only seems big because we humans are tiny and insignificant little beings.

It's also important to remember how utterly unimportant we are in the grand scheme of things:

This year's Earth Day is also a little different from those in the past few decades:

Also, we need not fear meteors, because they're much more common than we think:

Not only are we humans insignificant, but we also underestimate the power of Earth:

Finally, Tyson posted an interesting video looking at Earth from the perspective of rocks:

Happy Earth Day!
