DMPP-7 b
DMPP-7 b is a hot Jupiter orbiting DMPP-7 in the constellation Virgo. It lies about 331 light-years from Earth and was discovered in 2026 using the radial velocity method.
Is DMPP-7 b in the Habitable Zone?
DMPP-7 b orbits inside the inner edge of the habitable zone of DMPP-7. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of DMPP-7: 1.221–2.854 AU (conservative: 1.546–2.706 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on DMPP-7 b
The equilibrium temperature of DMPP-7 b is about 1,456 K (1,183 °C) — hot enough to melt many metals. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C.
Orbit and Year Length
A year on DMPP-7 b — one full orbit around DMPP-7 — lasts 4.93 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.061 AU — closer to its star than Mercury is to the Sun. Its orbit is mildly elliptical (eccentricity 0.05).
How Was DMPP-7 b Discovered?
DMPP-7 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-7 b?
DMPP-7 b is 330.7 light-years (101.4 parsecs) from Earth. Light arriving here tonight left the planet around the year 1696. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 5,820,320 years to make the journey.

Frequently Asked Questions About DMPP-7 b
Is DMPP-7 b habitable?
No — DMPP-7 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is DMPP-7 b?
DMPP-7 b is about 331 light-years from Earth in the constellation Virgo. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 5,820,320 years to get there.
How long is a year on DMPP-7 b?
One orbit around DMPP-7 takes 4.9 Earth days — short enough that 74 of its years would fit into one Earth year.
