Comet Lemmon is a rare visitor that travels far into the solar system and was discovered by the Mount Lemmon Survey in Arizona. According to astronomers, such comets contain pristine material, much of which has remained unchanged since the solar system formed billions of years ago.

Its greenish colour is caused by the presence of diatomic carbon and cyanogen gases, which are illuminated by sunlight.
