Different altitudes – low Earth orbit (LEO), medium Earth orbit (MEO), geostationary Earth orbit (GEO) – provide one variable, but elliptical (stretched out) orbits can support new use cases.

Satellites in LEO travel at speeds around 7.8 kilometres per second, which means they complete an orbit around Earth approximately every 90 minutes. As a result, the ISS orbits Earth about 16 ...

For example, 469219 Kamoʻoalewa is an asteroid about 50 meters wide in an orbit with a period of 1.002 Earth years—just around 17 hours longer than Earth’s period!

Some of these new, exotic orbits become quite stretched-out and elliptical—and, in some cases, these orbits can eventually bring these asteroids closer to Earth. When they do, “there is a ...
