Three high school students in Racine, Wisconsin, discovered an asteroid, temporarily identified as "2008 AZ28"

Sophomores Connor Leipold, Tim Pastika and Kyle Simpson were able to make the discovery thanks to technology provided from Calvin College in Grand Rapids, Mich., which is also the alma mater of the science teacher, Andrew Vanden Heuvel, school spokeswoman Susan Paprcka said.

"It’s extremely rare and I don’t know if an asteroid has ever been discovered by high school students before," Vanden Heuvel said. "Ninety-nine percent are discovered by professional researchers."
