NASA currently envisions the first two SLS flights, EM - 1 and 2, as part of the agency's Asteroid Initiative mission proposal, which aims to robotically redirect a small Near - Earth Asteroid into
orbit around the Moon by the end of the decade, to be later visited by human crews.

by looking at it, and they would wonder how it was possible.
The same side of the
Moon is almost always facing the Earth, but strictly speaking, it changes
by a slight amount according to the lunar
orbit around the Earth.
Unlike every other major satellite of every other planet in our solar system, our
moon ignores the axis of its parent planet and instead circles in nearly the same plane that Earth and the other planets
orbit around the sun, offset
by slightly over five degrees.
The
moon is a bonanza for scientists, Kring says, because it offers crucial insights for understanding the origins and evolution of Earth and other planets: how they formed from the accretion and differentiation of smaller bodies; how they were bombarded
by impacts early in their histories; and even how some of them migrated in their
orbits around the sun.
Through the newly invented telescope Galileo had seen many things that couldn't be explained
by the dominant cosmology of the time, rooted in the idea that all things revolved
around Earth: things like
moons crossing the face of Jupiter, or the changing phases of Venus as sunlight caught it at different angles — an impossibility if Venus's
orbit encircled Earth.
You know, for instance
around Earth, you can think of gravity as forming a kind of a well
around Earth, which causes the things that pass near Earth, the
moon I would say, which is
orbiting on its path, to stay within the vicinity because it falls into that gravity well, metaphorically speaking; and in likewise the same way this astronaut that is fictitiously described
by our good mathematics professor takes a journey through curved spacetime.

by the two organizations, the HDTV - equipped spacecraft Kaguya entered lunar
orbit last month and went on to shoot a combined eight minutes of crisp video (available here) from a distance of
around 60 miles (100 kilometers), offering a panoramic view of the
moon's northern topography.
By combining observational data from OGLE and Hubble, astronomers have been able to work out the nature of the star system, which is located
around 8,000 light - years away, to great precision The star system consists of two red dwarfs
orbiting one another only 7 million miles apart (as a comparison, this is only 14 times the Earth -
moon distance).
Cassini took nearly a half - million images during its mission, which included more than 13 years in
orbit around Saturn, a tour that repeatedly took the probe
by the
moons Titan and Enceladus, two places scientists are eager to send another spacecraft in the search for microbial life.
But while space enthusiasts wait for data and images to start pouring out — Juno's principal investigator, Scott Bolton, said all images shot
by the «Juno Cam» will be released to the public — NASA has published a time - lapse video of the Galilean
moons orbiting around Jupiter.
While a large impact on Uranus when it was still surrounded
by a protoplanetary disk would have eventually produced
moons in retrograde
orbit around the planet, two or more smaller collisions had a much higher probability of generating the
moons with the orbital direction observed today (Europlanet press release; and Phil Plait, Bad Astronomy Blog, Discover, October 7, 2011).
On December 1, 2009, two astronomers submitted a pre-print suggesting that the planet's extreme axial tilt (an obliquity of 97 degrees) may have resulted from the presence of a large
moon that has since been ejected from
orbit around the ice giant
by the pull of another planet during the orbital migration of the giant planets early in the formation of the Solar System.
The lunar nodes are determined
by the points where the
moon's
orbit crosses the «ecliptic» — the apparent path the sun makes
around the earth.

The Earth -
Moon doesn't
orbit the Earth -
Moon - Sun barycenter exactly but it is not
orbiting the barycenter of the solar sysem either; to some approximation the innermost planets and the sun must wobble
around the barycenter together as they are similarly affected
by the outermost planets which happen to be more massive as well as more distant and thus dominate in their effects on the barycenter — things should tend to get more complicated when the planets involved are at more similar distances.
