A red dwarf star in the eastern parts of Capricornus, lying to the north and across the Ecliptic from the more prominent stars Deneb Algedi and Nashira. As a red dwarf, Ross 206 is a far from luminous star, and it appears extremely faint as seen from Earth. With an apparent magnitude of +12.7, it is some five hundred times too faint to be seen with the naked eye.

According to its parallax measurement, Ross 206 lies some 105 light years from the Solar System. It is notable for its high proper motion against the sky (the factor that includes it in the Ross catalogue of New Proper Motion Stars). This star is moving southward across the sky at a rate of about 700 milliseconds of arc per year, which equates to a considerable half a degree per century.
