Vadim Zhytnikov and James Nester of National Central University in Chung - Li tried to construct a relativistic gravity theory which is able to explain both the orbital motion of stars in spiral galaxies and the bending of light while possessing the most general features possible (Physical Review Letters, vol 73, p 2950).

The elliptical orbit, called P / 2, is exactly half of the moon's orbital period; this means that TESS will orbit Earth every 13.7 days.

On March 5, 2015, a team of astronomers announced that numerical simulations constrain the size of planetary candidate Alpha Centauri Bb (with orbital period P = 3.24 days; and semi-major axis a = 0.042 AU) to less than 2.7 Earth - masses at an inclination of 45 to 53 degrees relative to Stars» AB orbital plane (Plavchan et al, 2015).

Abstract: We report the discovery of KELT - 20b, a hot Jupiter transiting a V ~ 7.6 early A star with an orbital period of P ~ 3.47 days.

F... ▽ More We report the discovery of KELT - 20b, a hot Jupiter transiting a V ~ 7.6 early A star with an orbital period of P ~ 3.47 days.

We refine the orbital period of this planet with new observations, obtaining $ P = 4.6403294 \ pm 0.0000055 \, \ mathrm -LCB- d -RCB- $.

Furthermore, we report the discovery of an additional non-transiting planet with a minimum mass of 19.96 +3.08 - 3.61 MEarth and an orbital period of ~ 34 days in the gap between Kepler - 20f (P ~ 11 days) and Kepler - 20d (P ~ 78 days).

Radial velocity measurements of Alpha Centauri B with High Accuracy Radial Velocity Planet Searcher spectrograph ruled out planets of more than 4 M ⊕ to the distance of the habitable zone of the star (orbital period P = 200 days).

The orbital period is P = 3.523 days and orbital semima jor axis is 0.0483 +0.0006 / -0.0012 AU.

Anyway it's linear, if you want to think of it in terms of sp hybridization the carbon has two sp orbitals (at 180º) forming sigma bonds with two pi bonds formed by the orthogonal p - orbitals.
