Question:
Dear Sir, I was thrilled and gratified to learn recently that a crater was named 'Tyagaraja', a great musician of the 17-18th centuries from South India. Here is a link from your website related to this. I would appreciate if you could share any information about how his name came to be chosen. For example, what was the process, who were the people involved in the selection etc. Many Thanks in advance. Regards, Prabhakar
Answer:
Tyagaraja is one of the most fascinating features on Mercury. The crater name was assigned by the International Astronomical Union (IAU) in 1976, based on images of Mercury's surface returned by NASA's Mariner 10 spacecraft. According the the IAU theme, impact craters on Mercury are named for "Deceased artists, musicians, painters, and authors who have made outstanding or fundamental contributions to their field and have been recognized as art historically significant figures for more than 50 years." The specific person who suggested this name may be lost to history, but the IAU strives to include worthy individuals from all over the world. So the name Tyagaraja was included based on his accomplishments.
If you would like to offer a suggestion for naming a crater on Mercury, you could enter the contest that is underway until January 15, 2015.
