MPC: confirming new moons, PgII

Key Highlights:

• The Minor Planet Centre (MPC) announced the discovery of 15 new moons: 4 orbiting Jupiter and 11 orbiting Saturn.
• Scott Sheppard and David Tholen discovered the Jovian moons, while Edward Ashton's team found the Saturnian moons.
• The MPC, located in Cambridge, Massachusetts, operates under the Smithsonian Astrophysical Observatory and the International Astronomical Union.

Detailed Insights:

• The MPC serves as the main global center for observations of small solar system bodies, including asteroids, comets, and planetary moons.
• Upon discovery of a new object, astronomers submit data to the MPC for verification, orbit calculation, and official designation, ensuring a unique identity and predictable path.
• A key function of the MPC is monitoring Near-Earth Objects (NEOs) with support from NASA’s Planetary Defense Coordination Office, predicting potential Earth threats.
• The MPC disseminates information through electronic circulars, enabling global coordination among researchers for data collection on celestial events.

Key Concepts Involved:

• Minor Planet Centre (MPC): The official body responsible for designating minor planets and other small bodies in the solar system.
• Near-Earth Objects (NEOs): Asteroids and comets with orbits that bring them close to Earth.
• International Astronomical Union (IAU): An international organization of professional astronomers.
