Based on data from the NASA exoplanet archive, Eyes on the Exoplanet enables uses to zoom in on more than 1000 planets orbiting distant stars.Exoplanets can be filtered by relevant criteria such as Earth-sized, large rocky planets, gas giants, etc. Distances to these planets are expressed in travel time by car, plane, etc. [9]
On 6 January 2020, NASA reported the discovery of TOI-700 d, the first Earth-sized exoplanet in the habitable zone discovered by the TESS. The exoplanet orbits the star TOI-700 100 light-years away in the Dorado constellation. [80] The TOI-700 system contains two other planets: TOI-700 b, another Earth-sized planet, and TOI-700 c, a super-Earth.
An exomoon or extrasolar moon is a natural satellite that orbits an exoplanet or other non-stellar extrasolar body. [ 2 ] Exomoons are difficult to detect and confirm using current techniques, [ 3 ] and to date there have been no confirmed exomoon detections. [ 4 ]
K2-18b, also known as EPIC 201912552 b, is an exoplanet orbiting the red dwarf K2-18, located 124 light-years (38 pc) away from Earth.The planet is a sub-Neptune about 2.6 times the radius of Earth, with a 33-day orbit within the star's habitable zone.
NASA's Galileo ' s measurements suggest that large moons can have magnetic fields; it found Ganymede has its own magnetosphere, even though its mass is only 2.5% of Earth's. [18] Alternatively, the moon's atmosphere may be constantly replenished by gases from subsurface sources, as thought by some scientists to be the case with Titan. [21]
NASA's profile of 2024 PT5. NASA Eyes on Asteroids ... For reference, the main moon (the big one you see in the sky at night) is, on average, about 238,855 miles (384,400 kilometers) ...
Artist's concept of exomoon Kepler-1625b I orbiting exoplanet Kepler-1625b.Kepler-1625b I could theoretically have a subsatellite itself. [1] [2]A subsatellite, also known as a submoon or informally a moonmoon, is a "moon of a moon" or a hypothetical natural satellite that orbits the moon of a planet.
HD 189733 b is an exoplanet in the constellation of Vulpecula approximately 64.5 light-years (19.8 parsecs) away [7] from the Solar System.Astronomers in France discovered the planet orbiting the star HD 189733 on October 5, 2005, by observing its transit across the star's face. [1]
