NASA's Stardust mission successfully flew within 236 … WebAs a rule of thumb, comets are about 10 km in diameter. Halley is about 16 x 8 x 8 km; Hale-Bopp was one of the biggest comets every seen, with a diameter twice that of Halley. But the typical comet is about 10 km in size, but of course is odd shaped since such small objects will not be spherical shaped. What is the mass of a comet?
WebThe Halley Armada. As Halley's comet arrived near the Sun in 1986 on its 76-year orbit, it was met by spacecraft from Japan, Europe, and the USSR. Comet enthusiasts lamented the absence of the USA from this once-in-a-lifetime opportunity. Japan's Suisei and Sakigaki made distant observations of the ultraviolet coma. WebComets travel in an orbit; a short orbital-period comet is one that takes 200 years or less to go around the Sun, and a long orbital-period comet takes more than 200 years—often thousands or even millions of years. Halley's Comet is a short orbital-period comet that can be seen from Earth every 75 to 76 years.
