Elara is one of the moons of Jupiter, the largest planet in our solar system. It was discovered in 1905 by the astronomer Charles Dillon Perrine. Elara is classified as a non-spherical moon and is part of the Himalia group, which consists of several irregularly shaped moons that share similar orbits. Elara has a diameter of about 86 kilometers (53 miles) and orbits Jupiter at a distance of approximately 11 million kilometers (6.8 million miles). Its surface is believed to be composed mainly of ice and rock, and it has a relatively low albedo, meaning it reflects only a small amount of sunlight.
