Talk:High Earth orbit

Merge

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 18:50, 5 September 2006 (UTC)

HEO stands for Highly Elliptical Orbit; no-one uses it as 'High Earth'. This page should be deleted. Lloyd Wood 22:42, 1 November 2006 (UTC)

Agree. At a minimum remove HEO as a bogus abbreviation for High Earth Orbit. None of the sources support that.

High Earth orbits are either Highly Eliptical Orbits (true HEOs), GEO, GSO, GTO, or in a Earth-Sun L1 or L2 or possibly some complex Earth-Moon orbits.

The only high circular orbits are either GEO or GEO graveyard orbits. Zygerth (talk) 03:51, 12 June 2024 (UTC)

I've reinserted the original redirect to Highly Elliptical Orbit. The previous content of this article was completely bogus - even the cited NASA reference did not use 'High Earth orbit' in this way - and no-one else does, either. Some reality-check rhetorical questions, before the reader attempts a knee-jerk revert: if the so-called "High Earth orbit" is really above 2000 km to distinguish it from Low Earth Orbit, how does Medium Earth Orbit fit in? What's the Earth's Moon in, then? A very high orbit?

Taka2007, thankyou for providing the expected knee-jerk revert to High Earth Orbit. At least you had second thoughts about it. But it's clear that you have no particular knowledge in this area.

High Earth Orbit vs Highly Elliptical Orbit

I have corrected the confusion between the two terms present in various articles. See Talk:Geocentric orbit for a discussion. Morana (talk) 10:06, 8 May 2008 (UTC)

Definition

There is some discussion on the proper definition of High Earth orbit. It started at User_talk:Roentgenium111#High_Earth_orbit and continues at Talk:Geocentric_orbit#High Earth Orbit vs Highly Elliptical Orbit. Note, this explains the "not in citation given" tag.

Inappropriate picture

The lead picture on this page depicts orbits within the geostationary orbit, while the lead sentence defines LEO as outside the geostationary orbit. Therefore it is inappropriate for what it is supposed to illustrate, and needs to be changed. JustinTime55 (talk) 16:42, 10 December 2013 (UTC)

Cleanup needed in section "Common types of high Earth orbits"

The paragraph starting with "There are four main reasons that most satellite are placed in lower orbits" needs a cleanup, because:

• Unencyclopedic prose
• Placed in incorrect section (title is "Common types of high Earth orbits")
• Is a listing of pros/cons
• Does not use SI units
• Opinionated phrases such as "useless for internet, and hard to use for other things as well"

I added the section cleanup tag to raise visibility, please remove or change the tag if another is better suited. 77.250.67.54 (talk) 00:08, 22 July 2024 (UTC)

Orbital parameters wrong?

It looks to me as if only the initial inclinations (& maybe more; didn't check anything else) for each satellite are given, not the current ones.

I'm a rank amateur, and hence very possibly mistaken; or perhaps we don't care about the current data, and hence only list the orbit an object was initially launched into; so I didn't change any of these — just thought I'd note it here in case someone who, say, knows what "TLEs" are without having to Google the term (i.e. not me, heh) wants to check.
