A mysterious object discovered in September is currently a new mini-moon for Earth. NASA confirmed on Tuesday, December 2, that the object is a lost-and-found 60s-era rocket from the Surveyor 2 moon mission, launched from Earth more than 50 years ago.

China’s robotic Chang’e 5 launched successfully last week atop a Chinese Long March 5 rocket. Now it’s reported to have landed on the moon. It’s scheduled to bring back moon rocks later this month.

Where did the famous mystery Wow! signal, detected in 1977, come from? Astronomer Alberto Caballero might have pinpointed the host star. It’s a sunlike star 1,800 light-years away, in the direction of the center of our Milky Way.

Asteroid 2000 WO107 passed Earth safely on November 29, at 11 times the moon’s distance. Astronomers at Goldstone bounced radar signals from its surface and discovered it’s 2 asteroids that touched, and stuck.
