Philae ( / ˈfaɪliː / [ 6] or / ˈfiːleɪ / [ 7]) was a robotic European Space Agency lander that accompanied the Rosetta spacecraft [ 8][ 9] until it separated to land on comet 67P/Churyumov–Gerasimenko, ten years and eight months after departing Earth. [ 10][ 11][ 12] On 12 November 2014, Philae touched down on the comet, but it bounced ...

A washing machine (laundry machine, clothes washer, washer, or simply wash) is a machine designed to launder clothing. Modern-day home appliances use electric power to automatically clean clothes. The term is mostly applied to machines that use water as opposed to dry cleaning (which uses alternative cleaning fluids and is performed by ...
C/2014 UN 271 is the second-largest known comet, being only behind 95P/Chiron. Radio thermal emission measurements by the Atacama Large Millimeter Array (ALMA) in 2021 estimate a maximum diameter of 137 ± 17 km (85 ± 11 mi) for C/2014 UN 271 's nucleus, assuming negligible contamination of the nucleus's thermal emission by an unseen dust coma ...
Rosetta was the first spacecraft to orbit a comet nucleus, [ 51 ] and was the first spacecraft to fly alongside a comet as it headed towards the inner Solar System. It became the first spacecraft to examine at close proximity the activity of a frozen comet as it is warmed by the Sun.
Halley's Comet is the only known short-period comet that is consistently visible to the naked eye from Earth, [16] appearing every 72–80 years. [17] It last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061. Officially designated 1P/Halley, it is also commonly called Comet Halley, or sometimes simply Halley.
The Community of Metros Benchmarking Group ( COMET ), formerly CoMET and Nova groups, is a multinational collection of metro systems focusing on international benchmarking, facilitated by the Transport Strategy Centre (TSC) at Imperial College London. The Community of Metros consist of 42 metro systems in 39 cities around the world.
Giotto. (spacecraft) Giotto was a European robotic spacecraft mission from the European Space Agency. The spacecraft flew by and studied Halley's Comet and in doing so became the first spacecraft to make close up observations of a comet. On 13 March 1986, the spacecraft succeeded in approaching Halley's nucleus at a distance of 596 kilometers.
