Astronomers Set Out to Find the Sun's Long Lost Sibling - And Succeeded
When Ivan Ramirez started his search about a year ago, he really didn’t think he’d find much.
"We expected it to be either one or zero," says Ramirez, an astronomer at UT-Austin.
Ramirez and his crew were looking through thousands and thousands of stars – all in order to find just the right one.
“We're looking for the stars that were born with the sun," he says. "Because our sun, like most other stars, was born in a cluster – probably a thousand to ten thousand other stars. We know that there are a few that we can detect that are nearby, but it’s been a really tough job to do."
They were surprised when they actually found one. A star named HD 162826. You can actually see it in the night sky with some binoculars – near the star Vega. It's the sun’s sibling.
KUT's Matt Largey talks with Ramirez about the find.
