Orbit and Rotation
This small world, due to being between 3.03 and 3.27 AUs (astronomical units), is a member of the outer asteroid belt, and the outer region of that, and is thus one of the most distant non-Jupiter Trojan asteroids. It is also, as previously mentioned, a member of the Eos family of asteroids. At 9.734°, 513 Centesima has a relatively small inclination to the ecliptic, less than the asteroid and dwarf planet, Ceres, the largest asteroid. It orbits the sun in 5.239 years. Its' aphelion is 3.255 AU's, and its' perihelion is 2.777 AUs from the sun. It has a surprisingly circular orbit, with an eccentricity of about .079. It reached epoch, a place in an objects' orbit that is useful for good study, on August 18, 2005, almost 98 years after discovery,only 6 days before a full 98 years, to start a 99th year. Its' rotation remains unknown.

Famous quotes containing the words orbit and, orbit and/or rotation:
“Words can have no single fixed meaning. Like wayward electrons, they can spin away from their initial orbit and enter a wider magnetic field. No one owns them or has a proprietary right to dictate how they will be used.”
—David Lehman (b. 1948)
“The Fitchburg Railroad touches the pond about a hundred rods south of where I dwell. I usually go to the village along its causeway, and am, as it were, related to society by this link. The men on the freight trains, who go over the whole length of the road, bow to me as to an old acquaintance, they pass me so often, and apparently they take me for an employee; and so I am. I too would fain be a track-repairer somewhere in the orbit of the earth.”
—Henry David Thoreau (1817–1862)
“The lazy manage to keep up with the earth’s rotation just as well as the industrious.”
—Mason Cooley (b. 1927)
