Big



The Artemis spacecraft just recently reentered earth's atmosphere traveling at 25,000 miles per hour. That's one trip around the entire earth every hour. 

That's 6.9 miles per second. Pretty fast. 13.4 times faster than a bullet. 

Traveling at 25,000 mph it would take Artemis 115,000 years to get to the nearest star 4.3 light years away. 

There are trillions of stars.
