Look up at the sky on a clear night, and you’ll see lots of stars. Sometimes they seem almost within reach or at least a short rocket ride. But the closest star to Earth—not counting our sun—is

Scientist anticipated “snowman” asteroid appearance

The figure shows paintings that Hartmann made from 1978 to 1996, to illustrate the possible outcome of very low-velocity

Two mini-rovers have sent their first pictures back from the surface of the asteroid Ryugu, a day after they were dropped off by Japan’s Hayabusa 2 spacecraft.

The pictures are blurry because they were taken while the rovers were falling and hopping around the half-mile-wide asteroid, more than 180 million miles from Earth. The rovers are built to spring up from the surface repeatedly and hop as far as 50 feet at a time. A

Kick Asteroid: Planetary Defenders, Earth Needs You!

The Planetary Society is excited to partner with space artist and designer, Thomas Romer, and backers around the world to create Kick Asteroid—a colorful graphic poster that will illustrate the effect of past catastrophic impacts, and methods to deflect future asteroid threats. Compelling and scientifically accurate art will be created for posters and other “merch” that backers can use in their everyday lives to spread the word about
