Comet to pass earth, visible to naked eye

Star gazers are in for a rare treat Monday night.

Another comet is zipping by earth but this one is visible to the naked eye.

Comet Pan-STARRS was discovered just two years ago.

We will get a chance to see it here around sunset.

Experts said the window to spot Pan-STARRS is small but will appear low on the western horizon about 8:15 p.m. Okla. time.
