This list of exoplanets discovered in 2024 is a list of confirmed exoplanets that were first reported in 2024. For exoplanets detected only by radial velocity , the listed value for mass is a lower limit.
Webb's First Deep Field was taken by the telescope's Near-Infrared Camera (NIRCam) and is a composite produced from images at different wavelengths, totalling 12.5 hours of exposure time.

Barring any incident, Pioneer 11 will pass near one of the stars in the constellation in about 4 million years. [3] Voyager 2 – launched in August 1977, flew past Jupiter in 1979, Saturn in 1981, Uranus in 1986, and Neptune in 1989. The probe left the heliosphere for interstellar space at 119 AU on November 5, 2018. [4] Voyager 2 is still active.
Notably, Artemis I represents the first time explorers intended to travel this far out — Apollo 13 only ventured so far from Earth because NASA's emergency flight plan required the Moon as a ...
It is currently the furthest man-made object from Earth, as well as the first object to leave the heliosphere and cross into interstellar space. As of November 2017 it has a distance from the Sun of about 140 astronomical units (AU) [ 10 ] (21 billion kilometers, or 0.002 light years), and it will not be overtaken by any other current craft.
