Astronomers have discovered a cache of 14 large space rocks beyond the orbit of Neptune while sifting through archival observations from the Hubble Space Telescope.
Icy rocks like the newfound objects are known as trans-Neptunian objects because they typically reside outside Neptune's orbit. These objects include the former planet Pluto, now classified as a dwarf planet, as well as comets like the famed Halley's comet.
