What is Churyumov-Gerasimenko made of?
The composition of water vapor from Churyumov–Gerasimenko, as determined by the Rosetta spacecraft, is substantially different from that found on Earth. The ratio of deuterium to hydrogen in the water from the comet was determined to be three times that found for terrestrial water.
How did the comet called 67P Churyumov-Gerasimenko get its name?
Like all comets, Churyumov-Gerasimenko is named after its discoverers. It was first observed in 1969, when several astronomers from Kiev visited the Alma-Ata Astrophysical Institute in Kazakhstan to conduct a survey of comets.
Where is comet 67P in the solar system?
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.
Who discovered 67P?

Klim Churyumov

Is it possible for an asteroid to hit Earth?
Currently none are predicted (the single highest probability impact currently listed is ~7 m asteroid 2010 RF12, which is due to pass earth in September 2095 with only a 5% predicted chance of impacting). Currently prediction is mainly based on cataloging asteroids years before they are due to impact.
Where is 67P now?
Comet 67P/Churyumov-Gerasimenko is currently in the constellation of Cetus.
Is a comet bigger than LA?
NASA lands things on much larger stuff all the time, but at 2.2-by-2.5 miles in size, comet 67P/C-G seems just the right size for a little prince. That’s 67P/C-G Photoshop-looming over Los Angeles, as if to prove that there are more things in heaven and earth than are dreamt of on Sunset Boulevard.
Can we leave the Oort Cloud?
If those distances are difficult to visualize, you can instead use time as your ruler. At its current speed of about a million miles a day, NASA’s Voyager 1 spacecraft won’t enter the Oort Cloud for about 300 years. And it won’t exit the outer edge for maybe 30,000 years.
What is the mass of the Churyumov Gerasimenko comet?
It is estimated that currently a layer with an average thickness of about 1 ± 0.5 m (3.3 ± 1.6 ft) is lost per orbit. The comet has a mass of approximately 10 billion tonnes. The two-lobe shape of the comet is the result of a gentle, low-velocity collision of two objects, and is called a contact binary.
Where did the name Churyumov Gerasimenko come from?
Like all comets, Churyumov-Gerasimenko is named after its discoverers. It was first observed in 1969, when several astronomers from Kiev visited the Alma-Ata Astrophysical Institute in Kazakhstan to conduct a survey of comets.

When did Rosetta rendezvous with Churyumov Gerasimenko?
Churyumov–Gerasimenko was the destination of the European Space Agency’s Rosetta mission, launched on 2 March 2004. Rosetta rendezvoused with Churyumov–Gerasimenko on 6 August 2014 and entered orbit on 10 September 2014.
