4543 Phoinix is a large Jupiter trojan from the Greek camp, approximately 63 kilometers (39 miles) in diameter. It was discovered on 2 February 1989, by American astronomer Carolyn Shoemaker at the Palomar Observatory in California.[1] The assumed C-type asteroid is possibly elongated and has a longer-than-average rotation period of 38.9 hours.[4] It is one of the 60 largest Jupiter trojans and was named after Phoenix (Phoinix) from Greek mythology.[1]
