That’s 1.88 Earth years, which puts Mars and Earth reasonably close to an orbital resonance of 2:1. So just over every two years Earth catches-up on Mars and the planets briefly line-up.

Another important aspect of orbital dynamics is the study of resonances, particularly the 2g+h resonance in medium-Earth orbit (MEO). This research has focused on understanding the separatrices ...

And, their weight and design mean they can also travel beyond Earth’s immediate neighborhood, potentially ferrying humans to the moon, Mars, and beyond. By moving into orbit with its Commercial ...
