The close-up image, covering the inner 1 degree of the comet , shows a prolonged radius vector extending to the left. This dramatic image shows the nucleus of Halley's Comet and the surrounding coma as viewed by the Halley Multicolor Camera on the Giotto spacecraft. The fan-shaped set of streamers extending toward the sun from the coma is composed of dust jets being blown off the comet's nucleus by the sublimation of its ices. Giotto was sent by the European Space Agency to observe the comet. This meteorite was collected from the Allan Hills in Antarctica.
Meteorites are bits of rock that are captured by a planet's gravity and pulled to the surface.
This meteorite is of a type named chondrite and is thought to have formed at the same time as the planets in the solar nebula, about 4.55 billion years ago. Achondrite Meteorite Discovered at Reckling Peak, Antarctica, this type of meteorite is known as an achondrite . It has a basaltic composition and was probably formed when an asteroid melted about 4.5 billion years ago. The asteroid broke up some time later and this small piece of the asteroid was captured by Earth's gravity and fell to the ground. This iron meteorite was found at Derrick Peak, Antarctica.
