Show J 66 Mmvate any a student at i Indiana University has his feet on the ground and his head in the clouds. For as darkness settles over Bloom- ington, astronomy students enter the university's Link Observatory for another session with the stars. What makes the school's astronomy department un- usual is its relentless hunt for asteroids, earth's pint-sizsister planets. With help from the Army and Navy as well as the National Science Foundation, Indiana University has the only U. S. observatory that systematically searches for these scraps of real estate circling the sun. It's been a successful search, too. Besides locating a number of new asteroids, the department has rediscovered ed ... Eyes by Hugh Ilazelrigg X system is an asteroid habit. One of the most recent to be identified at Indiana was "Athalia," which was originally discovered by astronomers at Heidelberg University in 1903 and hadn't been seen since. Another little planet diswas found after a ar appearance. And thanks to the Bloomington space sleuths, earth has a sister planet named "Indiana" in honor of its discoverers.

"We felt a moral obligation to take on the job," says Prof. Frank K.

From these observations, the body's path around the sun can be computed to see if it is truly a new discovery.
