An asteroid known as 1994 PC 1 is set to fly by Tuesday 1.98 million kilometres from Earth, according to NASA Asteroid Watch.

The asteroid was first discovered in August, 1994 by astronomer Robert McNaught, and is about one kilometre wide.

This passing is the closest for the asteroid since January, 1933, and chances are if you are in a location without a lot of light pollution, you will be able to see it with a small telescope or even binoculars.

Due to the speed of the asteroid, Canadians and others in North America have the best chance to see 1994 PC1 at dusk.

If weather doesn’t permit your viewing, the Virtual Telescope Project has you covered with a live webcast following the asteroid.

NASA also allows users to track the asteroid in its 3D modelling of our solar system and asteroids online.
