How to reach the orbital configuration of the inner three planets in HD 40307 Planet System ? The formation of the present configuration of three hot super-Earths in the\nplanet system HD 40307 is a challenge to dynamical astronomers. With the two\n... YY Chen,JL Zhou,YH Ma - 中国科学...
We also find some special characteristics for each\nroutine. If the system went through pairwise 2:1 MMRs at the beginning, the MMR\nof the outer two planets would be broken first to reach the current state. As\nfor routine (iii), the planets would be out of the Laplace Resonance at...

The time it takes to get from one celestial body to another depends largely on the energy that one is willing to expend. Here "energy" refers to the effort put in by the launch vehicle and the sum of the maneuvers of the rocket motors aboard the spacecraft, and the amount of propellant...
to humor me. The metaphor was drawn from the orbital trajectory that electrons follow. While circling the same atom's nucleus their trajectories invariably overlap. In my mind, the college campus served as that nucleus. With this knowledge, I could stand back and watch a shell route collision...

The reason why we cannot see the entire illuminated hemisphere of the Moon during some Full Moons is that the Moon’s orbit around Earth is inclined at an angle of about 5° in relation to the Earth’s orbital plane, theecliptic. If the Full Moon occurs at a moment when the Moon is ...
The two orbital maneuvering systems' (OMS) engines are located in pods on the aft section of the orbiter, one on either side of the tail. These engines place the shuttle into final orbit, change the shuttle's position from one orbit to another, and slow the shuttle down for re...
How do you find the altitude and azimuth of a star? Celestial Coordinates: In order to describe the position of a star, a planet or any other astronomical objects, we need to use a well defined coordinate system. They might be a horizontal system which uses azimuth angle and altitude as ...
Wait until the capsule's speed drops below 200 m/s, or the parachute sign on the left turns from red to grey, and deploy the parachute. Common problems and solutionsRocket tumbles or goes out of controlThe most common problem of new players is their rockets going out of control while in...
