What are the white streaks on Churyumov Gerasimenko?
The white streaks reveal the dust grains as they flew in front of Rosetta’s camera over the course of a 146 second exposure.
Where is 67P Churyumov Gerasimenko now?
constellation of Cancer
Comet 67P/Churyumov-Gerasimenko is currently in the constellation of Cancer. The current Right Ascension is 09h 15m 06s and the Declination is +19° 50′ 42”.
What does 67P mean in comet?
67P/Churyumov–Gerasimenko (abbreviated as 67P or 67P/C–G) is a Jupiter-family comet, originally from the Kuiper belt, with a current orbital period of 6.45 years, a rotation period of approximately 12.4 hours and a maximum velocity of 135,000 km/h (38 km/s; 84,000 mph).
What is the largest comet?
Comet C/2014 UN271
The comet, officially known as Comet C/2014 UN271, is the largest such object ever observed by astronomers, Jewitt said. Its nucleus — the solid center, which is typically made up of ice, rock and dust — is about 85 miles across.

Where does Churyumov Gerasimenko come from?
Churyumov-Gerasimenko loops around the Sun in an orbit that crosses those of Jupiter and Mars, approaching but not reaching Earth’s orbit. Like most Jupiter Family comets, it is thought to have fallen from the Kuiper Belt, a region beyond Neptune’s orbit, as a result of one or more collisions or gravitational tugs.
Is there oxygen in the coma of comet 67P/Churyumov–Gerasimenko?

What is the perihelion of Churyumov-Gerasimenko?
In November 2220 the comet will pass about 0.12 AU (18 million km) from Jupiter which will move perihelion inwards to about 0.8 AU (120 million km) from the Sun. Before Churyumov–Gerasimenko’s perihelion passage in 2009, its rotational period was 12.76 hours.
What is the acceleration of Philae on Churyumov Gerasimenko?
The acceleration due to gravity on the surface of Churyumov–Gerasimenko has been estimated for simulation purposes at 10 −3 m/s 2, or about 1/10000 of that on Earth. Because of its low relative mass, landing on the comet involved certain technical considerations to keep Philae anchored.
