Related Facts:-
- A group of astronomers and citizen scientists has discovered a giant planet like the Jupiter in a distant solar system.
- This Jupitor like planet designated as TOI-2180 b, is at only 379 light-years away from us.
- TOI-2180 b is a gas giant exoplanet that orbits a G-type star. Its mass is 2.755 Jupiters; it takes 260.8 days to complete one orbit of its star.
- Gas giant exoplanet TOI-2180 b is at a distance of 0.828 AU from its star, its discovery was announced in 2022.
- The planet’s orbital period around its host star make special among the sample of known giant exoplanets.
- The team spotted the world using data gathered by NASA’s Transiting Exoplanet Survey Satellite, or TESS.
- TESS spots exoplanets by finding very small and repeatable dips in a star’s brightness as it transits, or passes between the spacecraft and the star.
- While TOI-2180 b’s orbital period is not quite confirmed, scientists predict TESS will see the planet again in February 2022.
- Citizen scientists:
- NASA’s citizen science projects are collaborations between scientists and interested members of the public.
- Through these collaborations, volunteers (known as citizen scientists) have helped make thousands of important scientific discoveries.
