TOI-715 is a red dwarf star located 42 parsecs (140 ly) from the Earth in the constellation Volans, [note 1] very close to the southern celestial pole. [4] The star is smaller and cooler than the Sun and has an apparent magnitude of 16.7 and is too faint to be seen with the naked eye or even a small telescope.
This list of exoplanets discovered in 2023 is a list of confirmed exoplanets that were first reported in 2023. For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information. Name Mass (M J) Radius (R J) Period (days) Semi-major axis (AU) Temp. (K) Discovery method Distance (ly) Host star mass (M ☉) Host star temp. (K ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
GJ 1214 b (sometimes Gliese 1214 b, [6] also named Enaiposha since 2023 [2]) is an exoplanet that orbits the star GJ 1214, and was discovered in December 2009. Its parent star is 48 light-years (15 pc) from the Sun, in the constellation Ophiuchus. At the time of its discovery, GJ 1214 b was the most likely known candidate for being an ocean planet.
On May 10, 2016, NASA announced that the Kepler mission has verified 1,284 new planets. [20] Based on some of the planet's sizes, about 550 could potentially be rocky planets. Nine of these orbit in their stars' habitable zone. [20]
On 1 November 2023, Lucy successfully flew by its first target, the main-belt asteroid 152830 Dinkinesh, at a relative speed of 4.5 km/s (2.8 mi/s). [59] On the following day, NASA released images from the flyby and announced the discovery of a small satellite orbiting Dinkinesh. [60]
2023 DW is a near-Earth asteroid of the Aten group.It is approximately 50 meters (160 feet) in diameter, roughly the size of the asteroid that caused the Tunguska event, [a] and was discovered by Georges Attard and Alain Maury, from the MAP (Maury/Attard/Parrott) asteroid search program in San Pedro de Atacama on 26 February 2023, when it was 0.07 AU (10 million km) from Earth.

HD 209458 b is an exoplanet that orbits the solar analog HD 209458 in the constellation Pegasus, some 157 light-years (48 parsecs) from the Solar System.The radius of the planet's orbit is 0.047 AU (7.0 million km; 4.4 million mi), or one-eighth the radius of Mercury's orbit (0.39 AU (36 million mi; 58 million km)).
