Single Close Encounters Do Not Make Eccentric Planetary Orbits [PDF]
, 1996 The recent discovery of a planet in an orbit with eccentricity $e = 0.63 \pm 0.08$ around the Solar-type star 16 Cyg B, together with earlier discoveries of other planets in orbits of significant eccentricity, raises the question of the origin of these ...

Dynamical Friction and Orbit Circularization [PDF]
Symposium - International Astronomical Union, 1987 We study the change in shape of the orbit of a satellite sinking (because of dynamical friction) towards the center of a larger galaxy. the galaxy is assumed spherically symmetric with distribution function either isotropic or predominantly radial. the satellite is a softened point mass.

Imaging characteristics and image restoration method for large field circular scanning system
Results in Physics, 2021 Large field circular scanning system obtains remote sensing images by rotating scanning, which is one of the technical ways to effectively expand the field of view of geostationary orbit optical remote sensing imaging system.

On the Circular Orbit Approximation for Binary Compact Objects In General Relativity [PDF]
, 2003 One often-used approximation in the study of binary compact objects (i.e., black holes and neutron stars) in general relativity is the instantaneously circular orbit assumption.

Short-Term Comparison of Several Solutinos of Elliptic Relative Motion [PDF]
Journal of Astronomy and Space Sciences, 2007 Recently introduced, several explicit solutions of relative motion between neighboring elliptic satellite orbits are reviewed. The performance of these solutions is compared with an analytic solution of the general linearized equation of motion.

THE ORBIT OF CHARON IS CIRCULAR
The Astronomical Journal, 2012 We present a detailed analysis of the orbit of Charon where we show its orbit to be circular. This analysis explores the effects of surface albedo variations on the astrometry and the resulting errors in the orbital elements. We present two new epochs of data from the Hubble Space Telescope taken in 2008 and 2010 and combine that with a re-analysis of ...

High-speed escape from a circular orbit [PDF]
American Journal of Physics, 2021 You have a rocket in a high circular orbit around a massive central body (a planet or the Sun) and wish to escape with the fastest possible speed at infinity for a given amount of fuel. In 1929, Hermann Oberth showed that firing two separate impulses (one retrograde and one prograde) can be more effective than a direct transfer that expends all the ...
