When was the moon Xiangliu discovered by Csaba Kiss and his team?
Csaba Kiss and his team announced the discovery of Xiangliu on the 17th of October 2016 at the 48th Meeting of the Division for Planetary Sciences. The satellite had been visible in archival Hubble Space Telescope images taken as early as the 9th of November 2009.
How far does Xiangliu orbit from its parent body Gonggong?
Xiangliu orbits its parent body at a distance of roughly 5,000 kilometers based on prograde models derived from 2017 observations. This orbital path is highly eccentric with an orbital value of 0.29.
What are the physical dimensions and color properties of Xiangliu compared to Gonggong?
Photometric measurements taken in 2017 revealed that Xiangliu has a minimum diameter of 36 kilometers if it has an albedo of 1. The satellite is far less red than its parent dwarf planet with a V, I value of 0.64 compared to 1.38 for Gonggong.
When did the International Astronomical Union officially name Xiangliu?
The International Astronomical Union approved the name Xiangliu on the 5th of February 2020 through the Minor Planet Center. Csaba Kiss chose this nine-headed venomous snake monster from Chinese mythology as chief minister to the water god Gonggong.
How long does it take for Xiangliu to complete one revolution around Gonggong?
Xiangliu completes one full revolution every 25.22 days according to current calculations. Scientists believe this shape resulted from either intrinsic formation processes or slow tidal evolution over billions of years.
