Although sun synchronous orbit (SSO) proved to be a good candidate for most remote sensing applications due to its constant lighting conditions and global coverage, low inclined orbits are distinguished by long ground track especially if the target area of concern has horizontal rectangular border. ...

If identified with the last stable orbit of a disk, this would suggest that the black hole has a moderate spin. However, we note that both the laor and kerrd spectral models used for the disk and line emissions, assume an extremal spin of 0.998 and hence the actual value of the inner...
1996TLhas an orbital semimajor axis of 84, and is in an extremely eccentric and highly inclined orbit (= 0.58,= 24°). With a red magnitude20.9, it is the brightest trans-neptunian object yet found since Pluto and Charon. Its... J Luu,BG Marsden,D Jewitt,... - 《Nature》 被引量...

(2) Asteroids and meteoroids approaching the Earth-Moon system with a low velocity may have moved in a nearly parabolic orbit when they reached the lunar distance from the Earth at the time when the impacts which carved the lunar maria took place. The investigation gives, therefore, not only...
Numerical simulations under the real force model were carried out, which not only validate the theoretical analysis and also give some valuable results for the orbit design of the LMOs.中国天文和天体物理学报:英文版Hai-HongWangLinLiuA Study on the Relationship between the Orbital Lifetime and ...
