Rho Indi b is an exoplanet that orbits around Rho Indi. Its semimajor axis is 2.54 AU placing just outside the star's habitable zone. The planet takes 3.7 years to orbit the star. It is over twice as massive as Jupiter. Since the inclination of the orbit to the line-of-sight was initially unknown, only a lower bound on the planet's mass could be determined.[1] In 2023, the inclination and true mass of Rho Indi b were determined via astrometry.[2]
