掠日彗星 Sungrazing comet

(重定向自Sungrazer)

掠日彗星是指近日点极接近太阳的彗星,其距离可短至离太阳表面仅数千公里。较小的掠日彗星会在接近太阳时被完全蒸发掉,而较大的彗星则可通过近日点多次。但太阳强大的潮汐力通常仍会使它们分裂。

英语百科

Sungrazing comet 掠日彗星

(重定向自Sungrazer)
The representative orbit of a sungrazing comet.
Comet ISON[19] taken with the Wide Field Camera 3 on April 30, 2013.[20]

A sungrazing comet is a comet that passes extremely close to the Sun at perihelion – sometimes within a few thousand kilometres of the Sun's surface. Although small sungrazers can completely evaporate during such a close approach to the Sun, larger sungrazers can survive many perihelion passages. However, the strong evaporation and tidal forces they experience often lead to their fragmentation.
