Don’t Miss a Rare Comet as It Shoots Across the California Sky

This one won’t be back for 7,000 years.

For the first time in nearly a quarter century, a comet will be visible to the unaided eye as it streams across the Northern Hemisphere. Named Neowise, the 3-mile long comet will get closest to earth on July 22 but will begin to fade away as it heads back into the solar system. According to MSN, the comet will be most visible to us on evenings between now and Sunday.

“Most comets are very far away, but every once in a while one will get directed inward and come in very close to the sun and sometimes close to the Earth,” said Andrew Fraknoi, an astronomy professor at the University of San Francisco’s Fromm Institute. “That rare event, when a chunk of ice actually makes an orbit where we can see it, where it’s both illuminated by the sun and relatively close to us, that’s pretty rare. That’s what everybody is excited about.”
