Planets that form in circumstellar disks are expected to have nearly circular orbits, although gravitational interactions in a system of two or more planets could generate high-eccentricity orbits. Here we suggest that the eccentric orbit of 16 Cyg Bb arises from gravitational interactions with the ...
hiatuses (breaks in sedimentation) from the global ocean spanning 70–0 Ma based on the compilation of Dutkiewicz and Müller19from 293 scientific deep-sea drill holes (Fig.1; see “Methods” section). Our analysis shows the presence of ~2.4 Myr eccentricity cycles linked to orbitally-pace...
The 2.4 Myr (g4–g3) eccentricity cycle related to the precession of the perihelions of Earth (g3) and Mars (g4), and the 1.2 Myr (s4–s3) obliquity cycle associated with the precession of the nodes of the two planets, are of particular interest5. Retrieving these signals from the ...
Interpreting information -verify that you can read information regarding the most eccentric planet in its orbit and interpret it correctly. Additional Learning To learn more about planets and their eccentricity, review the lesson called Eccentricity & Orbits of Planets. The lesson will cover the follow...

The orbits of the outer two known planets orbiting Upsilon Andromedae are remarkably eccentric. Planet C possesses an orbital eccentricity of e1 = 0.253. For the more distant planet D, e2 = 0.308. Previous dynamical analyses strongly suggest that the two orbits are nearly co-planar and are ...
A perfectly circular orbit has an eccentricity of zero. Elliptical orbits have values between 0 and 1 with higher values indicating a more eccentric orbit. An eccentricity of exactly 1 is a parabolic orbit and anything greater than that is a hyperbolic orbit. The orbits of the planets are ...
The 2.4 Myr (g4–g3) eccentricity cycle related to the precession of the perihelions of Earth (g3) and Mars (g4), and the 1.2 Myr (s4–s3) obliquity cycle associated with the precession of the nodes of the two planets, are of particular interest5. Retrieving these signals from the ...
area of an ellipse Orbits of Planets as ellipses Translate ellipse images Worksheet Version of this Web page (same questions on a worksheet) The eccentricity of an ellipse is a measure of how nearly circular the ellipse. Eccentricity is found by the following formula eccentricity = c/a where ...
In astronomy, eccentricity helps describe the orbits of planets and other celestial bodies, indicating how elongated a path a planet takes around its star. 14 In the context of mechanical engineering and manufacturing, concentricity is a critical tolerance that ensures the uniformity of the central ...
