Seeing comets with the naked eye from Earth is rare, so it is likely that there are currently no comets visible. Astronomers expect at least three comets will be visible from Earth in 2015.Know More
The comets astronomers predict seeing from Earth in 2015 are 88P/Howell, C-2014 Q1 PanSTARRS and C/2013 US10 Catalina. The Howell comet should be visible from the southern hemisphere from April to May. PanSTARRS will be visible from the southern hemisphere beginning in July. Catalina is expected to be the only comet visible in the northern hemisphere. It will likely appear in November or December.
A comet becomes visible to the naked eye when its orbit takes it close to the sun. A comet absorbs solar energy and outgasses, creating a tail of gas and dust that reflects light.Learn more about Comets & Asteroids
Noted American author Samuel Clemens, known by his pen name Mark Twain, was born on Nov. 30, 1935, shortly after Halley's Comet was most visible on Earth on Nov. 16, 1835. He was widely quoted as saying that he "would go out with it."Full Answer >
Halley's comet takes 76 years to pass by Earth. This comet is an example of a short-period comet, one whose orbit is influenced by the gravities of the outer planets of the solar system and so usually stays within the area of the planets.Full Answer >
Meteors from Mars arrive on Earth as the result of impacts on the planet by other bodies, which launch material out into space. Some of this debris is pulled in by the gravity of the Earth, falling as Martian meteorites.Full Answer >
A comet is composed of dust, ammonia, ice, carbon dioxide and methane in addition to other substances. Ice and dust covered with an organic substance largely make up the nucleus of a comet. The tail of a comet consists of dust and gas.Full Answer >
