Rock Star: Asteroid Named after APL’s Carolyn Ernst
After years of studying asteroids, Carolyn Ernst now has one of the big space rocks named after her.
The International Astronomical Union and Minor Planet Center have approved the name “Ernst” for the asteroid designated 11008, honoring the contributions of the Space Exploration Sector planetary scientist. The name, along with several others honoring scientists from around the world, was announced recently at the 2017 Asteroids-Comets-Meteors meeting in Montevideo, Uruguay.
“I’ve been fascinated by the solar system since I was a kid, so it’s both humbling and awesome that my name now has a permanent place in it,” Ernst said. “I’m very thankful for this honor.”
The asteroid was discovered in 1981 by astronomer Schelte Bus at Siding Spring observatory in Australia. Estimated at 3.1 miles (5 kilometers) across, its orbit in the inner asteroid belt, just beyond Mars, takes it from 215 million to 267 million miles from the sun.
Ernst, who joined APL in 2008, researches impact cratering and the surface evolution of asteroids and other solar system objects. She’s the Europa Imaging System instrument scientist on the developing Europa mission and serves on the imaging teams of the Cassini, New Horizons and Hayabusa2 missions. Her mission list also includes science team duties on MESSENGER and Deep Impact.
