Neither orbit is perfectly circular; Earth has an orbital eccentricity of 0.0168, and Mars of 0.0934. The two orbits are not quite coplanar either, as the orbit of Mars is inclined by 1.85 degrees to that of Earth. The effect of the gravity of Mars on the cycler orbits is almost negligible, but that of the far more massive Earth needs to be ...

A lunar cycler or Earth–Moon cycler is a cycler orbit, or spacecraft therein, which periodically passes close by the Earth and the Moon, using gravity assists and occasional propellant-powered corrections to maintain its trajectories between the two. If the fuel required to reach a particular cycler orbit from both the Earth and the Moon is ...
In December 2020, the Saudi Arabian Military Industries (SAMI) fully acquired AEC, making it a 100% Saudi-owned company. The deal shall strengthen SAMI's presence in the defense industries market.

The province is located in the center of Saudi Arabia approximately 400 km (250 mi) northwest of Riyadh, the capital. It is bordered by Riyadh Region to the south and east, by Ha'il Region to the north, and by Al Madinah Region to the west. The region is connected to almost every part of Saudi Arabia by a very complicated network of highways.
