Astronomers in Hawaii discover giant planet

MAUNA KEA, HAWAII (HawaiiNewsNow) - Astronomers atop the Big Island of Hawaii announced a major discovery on Monday: a giant planet.

The team of scientists found the newborn planet, called K2-33b, about 430 light years away and revolving around a different star from our sun.

Researchers say the planet is bigger than Neptune and is the youngest fully-formed planet ever discovered outside our solar system.

It is estimated to be five to ten million years old.

"At 4.5 billion years old, the Earth is a middle-aged planet — about 45 in human-years," said Trevor David, who authored a paper on the discovery. "The planet K2-33b would be an infant of only a few weeks old."

K2-33b orbits around its star in about five days and is nearly ten times closer to its star than our sun, NASA says.

Images from three telescopes, including Kepler Space Telescope and the W. M. Keck Observatory on Hawaii's Mauna Kea helped create a series of renderings of the planet released by NASA.
