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 year 2023 saw rapid growth and significant technical achievements in spaceflight. For the third year in a row, new world records were set for both orbital launch attempts (223) and successful orbital launches (211).
It was first observed on 19 May 2023 by Kōichi Itagaki and immediately classified as a type II supernova. [2] Initial magnitude at discovery was 14.9. [ 2 ] After discovery, the Zwicky Transient Facility project found a precovery image of the supernova at magnitude 15.87 two days before discovery. [ 9 ]

Psyche (/ ˈ s aɪ k i / SY-kee) is a NASA Discovery Program space mission launched on October 13, 2023, to explore the origin of planetary cores by orbiting and studying the metallic asteroid 16 Psyche beginning in 2029. [8] NASA's Jet Propulsion Laboratory (JPL) manages the project.
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.

The Trans-Earth Injection was done on 13 October 2023 with a targeted orbit of ~380,000 x 180,000 km. This was followed by four lunar flyby's with the last one on 7 November 2023. The module exited lunar SOI on 10 November 2023 and had the first perigee crossing on 22 November 2023 at an altitude of about 154,000 km. The propulsion module is ...
