Don't panic, but there will be another relatively large asteroid barreling past our planet tonight (July 29, 2013).

Asteroid 2003 DZ15 will come within 2.2 million miles of Earth this evening - far enough away that is will not effect us, but close enough that it may actually be visible - reports Yahoo.

Don't expect to be able to see it from your porch with just your eye, but the Virtual Telescope Project is streaming live video of the rock - estimated to be about 500-foot wide, the report says.

You can catch a live stream of the asteroid's passing of earth here, via the Virtual Telescope Project.

It is expected at 8:37 EDT this evening (7-29-130).
