Asteroid 2014 JO25 Echoes Back Its Secrets

The flyby provided the perfect opportunity for astronomers to study the physical properties of the asteroid and make images…

Only the dwarf planet Eris lies further. Both circle the sun in the scattered disk, a sparse ring of bodies that lies even farther than the Kuiper Belt, an…

I hope you had pleasant dreams overnight. In one of mine, I couldn’t get my shoe tied right. Glad I woke up from that one. While many of us slept, a tiny near-Earth asteroid named 2017 GM passed exceptionally close to Earth, just 9,942 (15,000 km) miles overhead at 5:31 a.m. CDT (10:31 UT). That…
