Astronomers in Hawaii have updated measurements of the Yarkovsky effect – a minuscule push imparted by sunlight – for asteroid Apophis. The effect is particularly important for Apophis, because it relates to the possibility of an Earth impact in 2068.

In November, a new mini-moon began orbiting Earth. NASA later confirmed it’s a lost-and-found 60s-era rocket from the Surveyor 2 moon mission, launched more than 50 years ago. Now the object – SO 2020 – is coming close again for one last time. Here’s how to see it!

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.

The asteroid – 2020 VT4 – is estimated to be between 16 and 36 feet (5-11 meters). It skimmed the top of our atmosphere on Friday, November 13, 2020. Astronomers spotted it one day later.

Discovered last June, Comet C/2020 M3 (Atlas) is closest to Earth – millions of miles away – on Saturday, November 14, 2020. It’s in an easy-to-find location, if you have a dark sky. Charts and photos here.

Watch online today as asteroid 2020 SW swoops in for its closest approach to Earth on Thursday. The asteroid will pass just 7% of the moon’s distance. Charts here for telescope users. How to watch online.

The orbit of asteroid 2011 ES4 is still not entirely known. Our knowledge of it might improve sometime today – or early tomorrow – if it is “recovered” by astronomers. It’s expected to pass within the moon’s orbit, possibly as close as 0.19 lunar distances.
