A giant asteroid flew past the Earth on Monday – the closest any space rock this large comes to us until 2027.

There was no need to panic; it safely passed by about three times the distance of Earth to the moon.

But it should still be visible in the night sky on Monday night using strong binoculars or a small telescope.

“I may grab my favorite binoculars and give it a shot myself,” said Don Yeomans, the retiring manager of NASA’s Near Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, California, in a blog post.

“While it poses no threat to Earth for the foreseeable future, it’s a relatively close approach by a relatively large asteroid, so it provides us a unique opportunity to observe and learn more.”

Here’s what you need to know about Asteroid 2004 BL86 and how to get the best look at it while you can:


1. How close?

There wasn’t much to see at 11.19 am when the asteroid was closest to Earth. The best chance for viewing is from 8 pm Eastern on Monday night to 1 am Eastern Tuesday.

It won’t be visible to the naked eye but some astronomers claim a pair of strong binoculars could do the trick.

“It will not be too far from Jupiter, which is very bright in the sky and rising as soon as it gets dark,” said Paul Chodas, who is taking over as NASA’s Near Earth Objects Program.
