Rosetta's Comet in View
Faint comet Churyumov-Gerasimenko (67P)
sweeps past background stars in the constellation Taurus and even fainter
distant galaxies in this telescopic frame from September 7.
About 5 years ago,
this comet's 4 kilometer spanning, double-lobed nucleus
became the final resting place of
robots from planet Earth,
following the completion of the historic Rosetta mission to the comet.
After wandering out beyond the orbit of Jupiter,
Churyumov-Gerasimenko is now returning along its 6.4 year
periodic orbit toward its next
perihelion or closest approach to the
Sun, on November 2.
On November 12, the comet's perigee, its closest approach to Earth,
will bring it within about 0.42 astronomical units.
Telescopes
should still be required to view it even at its brightest,
predicted to be in late November and December.
On September 7
Rosetta's comet
was about 0.65 astronomical units away or about 5.4 light-minutes
from our fair planet.
