Bizarre object found circling star. An object detected orbiting a neutron star is among the strangest planet-mass bodies ever found, astronomers said in September. Instead of circling around a normal star, the low-mass object—likely the "skeleton" of a smaller star—orbits a rapidly spinning pulsar, or neutron star. The odd mass, which was spotted on June 7 by NASA's Swift and Rossi X-ray Timing Explorer (RXTE) satellites, orbits the bigger star in a little less than once an hour.
