DMPP-6 b
DMPP-6 b is a super-Earth orbiting DMPP-6 in the constellation Volans. It lies about 178 light-years from Earth and was discovered in 2026 using the radial velocity method.
Is DMPP-6 b in the Habitable Zone?
The position of DMPP-6 b relative to the habitable zone of DMPP-6 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on DMPP-6 b — one full orbit around DMPP-6 — lasts 7.60 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.078 AU — closer to its star than Mercury is to the Sun. Its orbit is highly elliptical (eccentricity 0.34), swinging dramatically closer to and farther from its star.
How Was DMPP-6 b Discovered?
DMPP-6 b was discovered in 2026 using the radial velocity method, with observations from Multiple Observatories.
The radial velocity method measures the subtle wobble of a star caused by the gravitational pull of an orbiting planet, visible as periodic shifts in the star's light spectrum. The size of the wobble reveals the planet's minimum mass.
How Far Away Is DMPP-6 b?
DMPP-6 b is 178.2 light-years (54.6 parsecs) from Earth. Light arriving here tonight left the planet around the year 1848. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 3,136,320 years to make the journey.

Frequently Asked Questions About DMPP-6 b
Is DMPP-6 b habitable?
DMPP-6 b is not known to orbit within the habitable zone of DMPP-6, and as a super-Earth it is an unlikely candidate for life as we know it.
How far away is DMPP-6 b?
DMPP-6 b is about 178 light-years from Earth in the constellation Volans. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 3,136,320 years to get there.
How long is a year on DMPP-6 b?
One orbit around DMPP-6 takes 7.6 Earth days — short enough that 48 of its years would fit into one Earth year.
