Not heard this term used before, though I like the idea behind it. Maybe we just need to clean up the Earth orbit article rather than move to geocentric orbits. Earth orbit is more intuitive than geocentric orbits - Taka2007 18:51, 5 September 2006 (UTC)

I agree that "earth orbit" is a bit more intuitive, however it is a slang term used to describe geocentric orbits. I would say that we should redirect "earth orbit" to "geocentric orbit" since they are synonymous, but geocentric is more scientifically correct. Both support and rebuttal of this point would be appreciated.

Agree, the term is just "slang" and covers everything that's covered in this article, with less detail I might add. I think I might see what can be salvaged from the "Earth" article and redirect after merging. If I've been too bold just revert my changes. Radagast83 05:28, 11 November 2006 (UTC)

This page is a work in progress. More information and cleanup soon.

[edit] High Earth Orbit vs Highly Elliptical Orbit

I have corrected the existing confusion between the two terms by changing the relevant articles:

  • High Earth orbit
  • High Earth Orbit
  • Geocentric orbit
  • HEO

Here is a example of correct definitions:

A High Earth Orbit is any orbit above geosynchronous (above 35,786 km). A Highly Elliptical Orbit is an orbit of low perigee (about 1000 km) and a high apogee over 35,786 km).[1]

Some remarks:

  1. High Earth Orbit and Highly Elliptical Orbit are two different things.
  2. Highly Elliptical Orbits are a subset of High Earth Orbits.
  3. Some High Earth Orbit satellites are not in a Highly Elliptical Orbit. An example is given in High Earth Orbit.
