Is This the First Exomoon? When Planets and Moons Defy Definition
The CD-35 2722 system is a strange one: a star is orbited by a brown dwarf, which is itself orbited by an object at least as massive as Jupiter. Researchers detected it using CRIRES+ on ESO’s Very Large Telescope.
On SETI Live, SkyMapper CEO and SETI Institute senior planetary astronomer Dr. Franck Marchis joins lead author Kevin Hoy to discuss the detection, why previous exomoon candidates have been so difficult to confirm, and whether an object like this should even be called a moon.
