This March 2, 2013, photo made available by spaceweather.com shows the comet, Pan-STARRS, seen from Queenstown, New Zealand. The recently discovered comet is closer than it's ever been to Earth, and stargazers in the Northern Hemisphere finally get to see it. The comet passed within 100 million miles of Earth on Tuesday, March 5, 2013, its closest approach in its first-ever cruise through the inner solar system. The best viewing days should be Tuesday and Wednesday, March 12 and 13, when Pan-STARRS appears next to a crescent moon at dusk in the western sky. Until then, glare from the sun will obscure the comet. (AP Photo/spaceweather.com, Minoru Yoneto)

Twilight on Tuesday provided the best photo op for the comet called Pan-STARRS, visible in the Northern Hemisphere just above the western horizon — right next to a crescent moon.

Pan-STARRS was visible for weeks from the Southern Hemisphere before popping up on the upper half of the globe in recent days.

Although billions of year old, Pan-STARRS is making its first-ever cruise through the inner solar system. The ice ball passed within 28 million miles of the sun Sunday, its closest approach to our star and within the orbit of Mercury.

California astronomer Tony Phillips said the comet did not appear to decay during its brush with the sun, even though it encountered 10 times more intense solar rays than what we’re used to here on Earth.

Last Tuesday, Pan-STARRS made its closest approach ever of Earth.

The comet’s name is actually an acronym for the telescope in Hawaii used to discover it two years ago: the Panoramic Survey Telescope and Rapid Response System.

Astronomers believe Pan-STARRS somehow got kicked out of the Oort Cloud that is full of icy bodies beyond the orbits of Neptune and Pluto, and propelled into the inner solar system.

It will be visible in the Northern Hemisphere for weeks to come.

Have no fear: Pan-STARRS poses no threat to Earth. Neither does comet ISON, which promises to outdo Pan-STARRS.

Astronomers believe ISON will rival the moon in brightness, come November.
