HI-1A image of
comet
C/2011 W3 (Lovejoy)
in December 2011. The comet's
tail
is clearly interacting with the
solar wind
with several discontinuities visible. The
comet nucleus
of Lovejoy has been estimated to be between 100 and 200 meters (325 and 650 ft) in diameter. Notice the companion comet immediately above Lovejoy in the latter half of the sequence; it is speculated that this fragment
broke off
of Lovejoy several decades ago, due to the separation between the two.
