Look up and watch asteroid 1994 PC1 fly past Earth this week

n a slow moving universe, asteroids give us a rare chance to see things moving in real time.

We have such a chance coming right up on the evening of Tuesday, January 18, when 1.1-kilometer asteroid (7482) 1994 PC1 passes 1.23 million miles (1.98 million kilometers) from the Earth.

This is about five times the distance from the Earth to the moon, and just a shade over the distance to the anti-sunward Earth-sun Lagrange 2 point, soon to be the home of the James Webb Space Telescope.

The orbit of asteroid 1994 PC1.

This week's pass is the closest for the asteroid since January 17, 1933 (pre-discovery) at 0.00752 AU, and the closest for the next two centuries, although the pass on January 18, 2105 is nearly as close, at 0.01556 AU.

The path of the asteroid for the last 12 hours of January 17th.

The good news is, you can start hunting for 1994 PC1 tonight; the asteroid is still a respectable +12th magnitude plus on either evening before or after closest approach, January 17 or January 19.

Next 18 Jan. 2022, the Potentially Hazardous Asteroid (7482) 1994 PC1 will have a close, but safe, encounter with us, coming at about 2 millions of km from the Earth.

The Virtual Telescope Project will show it to you live, online: join us from the comfort of your home!
