Pallas (minor-planet designation: 2 Pallas) is the third-largest asteroid in the Solar System by volume and mass. It is the second asteroid to have been discovered, after Ceres , and is likely a remnant protoplanet .
Athena was a proposed space mission that would have performed a single flyby of asteroid 2 Pallas, the third largest asteroid in the Solar System. [1] If Athena had been funded, it was planned to share the launch vehicle with the Psyche and Janus spacecraft and fly its own trajectory for a Mars gravity assist to slingshot into the asteroid belt.
The Pallas family (adj. Palladian; FIN: 801) is a small asteroid family of B-type asteroids at very high inclinations in the intermediate asteroid belt. [1] [2] The family was identified by Kiyotsugu Hirayama in 1928.
First main-belt asteroid discovered to have an inclination greater than 2 Pallas. Most highly inclined known main-belt asteroid from August 30, 1935, to June 14, 1980 MPC: 1580 Betulia: 52.083° May 22, 1950 most highly inclined known minor planet from May 22, 1950, to July 4, 1973 MPC: 2938 Hopi: 41.436° June 14, 1980
Pallas, the largest B-type asteroid. Asteroid 101955 Bennu is a B-type asteroid which is the target of the OSIRIS-REx mission. The mission seeks to characterize the asteroid by mapping the surface, studying the Yarkovsky effect, and retrieving a sample of the asteroid to return in 2023. The spacecraft was launched in 2016 and has been at Bennu ...
The next largest are 4 Vesta and 2 Pallas, both with diameters of just over 500 km (300 mi). Vesta is the brightest of the four main-belt asteroids that can, on occasion, be visible to the naked eye. [70]
In March, NASA's James Webb Space Telescope will complete thermal imaging of 2024 YR4 which should help determine its size.. After April, Asteroid 2024 YR4 will be too faint for Earth-based ...
Dawn is a retired space probe that was launched by NASA in September 2007 with the mission of studying two of the three known protoplanets of the asteroid belt: Vesta and Ceres. [1] In the fulfillment of that mission—the ninth in NASA's Discovery Program — Dawn entered orbit around Vesta on July 16, 2011, and completed a 14-month survey ...
