NSVS 14256825 b
The parameters of this planet are disputed or ambiguous in the scientific literature.
NSVS 14256825 b is a exoplanet orbiting NSVS 14256825 in the constellation Aquila. It lies about 2,677 light-years from Earth and was discovered in 2019 using the eclipse timing variations method.
Is NSVS 14256825 b in the Habitable Zone?
The position of NSVS 14256825 b relative to the habitable zone of NSVS 14256825 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on NSVS 14256825 b — one full orbit around NSVS 14256825 — lasts 3,225.0 Earth days, longer than an Earth year. It orbits at an average distance of 3.120 AU. Its orbit is mildly elliptical (eccentricity 0.12).
How Was NSVS 14256825 b Discovered?
NSVS 14256825 b was discovered in 2019 using the eclipse timing variations method, with observations from Multiple Observatories.
Eclipse timing variations detect a planet orbiting an eclipsing pair of stars: the planet's gravity shifts the precise moments when the stars eclipse each other.
How Far Away Is NSVS 14256825 b?
NSVS 14256825 b is 2,677.3 light-years (820.9 parsecs) from Earth. Light arriving here tonight left the planet about 2,677 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 47,120,480 years to make the journey.
Earth Similarity Index
The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. NSVS 14256825 b scores 0.17, ranking #4,101 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
The Host Star: NSVS 14256825
NSVS 14256825 b is a circumbinary planet — it orbits around two stars at once, like Tatooine in Star Wars.
