Rosetta's Comet in Gemini
Returning along
its 6.4 year orbit,
periodic comet Churyumov-Gerasimenko (67P) is caught in this
telescopic frame from November 7.
Sweeping past background stars in the constellation Gemini
the comet's dusty tail stretches toward the upper right to Upsilon Geminorum.
Also known as Pollux,
Beta Geminorum, Gemini's brightest star,
shines just off the upper left edge of the field-of-view.
Churyumov-Gerasimenko
reached its 2021 perihelion
or closest approach to the Sun on November 2.
At perigee, its closest approach to planet Earth on November 12,
this comet was about 0.42 astronomical units away,
though it remains too faint to be seen by eye alone.
The well-studied comet
was explored by robots from planet Earth
during its last trip through the inner solar system.
It's now famous as the final resting place for the historic
Rosetta spacecraft and Philae lander.
