Description:
Comet Holmes (official designation: 17P/Holmes) is a periodic
comet in our solar system, discovered by the British amateur astronomer Edwin
Holmes on November
6, 1892. Although normally a very faint object, Holmes became
notable during its 2007 return when it temporarily brightened by a factor of
about half a million, in what was the largest known outburst by a comet, and
became visible to the naked eye. It also briefly became the largest object in
the solar system, as its coma (the thin dissipating dust ball around the comet)
expanded to a diameter greater than that of the Sun (although its mass remained
minuscule).(Wikipedia) |
