What is Hartley 2 made of?
Called hyperactive by the EPOXI mission, comet Hartley 2 spins around one axis, while tumbling around another one. Comet Hartley’s core is also not uniform, but is made up of water ice with methanol, carbon dioxide and possibly ethane. The release of these gases occur at different locations on the comet.
Where does comet Hartley come from?
Comet Hartley 2 is a small Jupiter-family comet having an orbital period of 6.46 years. It was discovered by Malcolm Hartley in 1986 at the Schmidt Telescope Unit, Siding Spring Observatory, Australia. It has the perihelion near the Earth’s orbit at 1.05 AU from the Sun.
