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 ...
This is a diffusing subcategory of Category:2023 in outer space. ... This list may not reflect recent changes. 0–9. C/2023 A3 (Tsuchinshan–ATLAS) 2023 AV; 2023 BU;
An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.
On 15 September, the Firefly Alpha made its successful flight for a tactically responsive mission for the U.S. Space Force. [27] On November 18, 2023, SpaceX Starship attempted its second flight test, becoming the heaviest rocket to enter space, although the first stage exploded shortly after separation, while the second stage was lost nearly ...
This discovery was found in studies of UHZ1, a very early galaxy containing a quasar, by the Chandra X-ray Observatory and James Webb Space Telescope. [622] [623] 29 November. Astronomers report the discovery of a star, HD 110067, that contains six sub-Neptune exoplanets with radii ranging from 1.94R⊕ to 2.85R⊕. [624]
A list of known near-Earth asteroid close approaches less than 1 lunar distance (0.0025696 AU (384,410 km; 238,860 mi)) from Earth in 2023. [1] As most asteroids passing within a lunar distance are less than 40 meters in diameter, they generally are not detected until they are within several million km of Earth.
Discovery 9 – Dawn, launched September 2007, completed – Vesta in 2011-2012, and Ceres in 2015-2018; Discovery 13 – Lucy, launched October 2021, operational – Will fly by one main-belt asteroid and seven Jupiter Trojan asteroids. [45] Discovery 14 – Psyche, launched October 2023, enroute; New Frontiers program
Most distant object when discovered; first quasar with z > 4. [105] [101] [110] [112] [113] Q1208+1011 (QSO B1208+1011) 1986–1987 z = 3.80 Most distant object when discovered and a gravitationally-lensed double-image quasar. From the time of discovery to 1991, had the least angular separation between images, 0.45″. [110] [114] [115] PKS ...
