===Orbiter 2001===

'''Halley's Comet''', also referred to as 1P/Halley, is a short period comet appearing in the skies every 72 to 80 years, last seen in 1986 and the next will be in 2061. Named after [[w:Edmond Halley|Edmond Halley]] who was the first to recognize it as a recurring comet although it has been seen since ancient times.

== Halley in Orbiter ==
−
Orbiter's 2002 release. Both files are needed for a working copy.
+
Halley was introduced to [[Orbiter]] as an add-on in 2004. Since Orbiter was not designed to show a comet's tails, the add-on depicts it as a rugby ball shaped body much like an asteroid.
−
{{Addon|
+
Halley orbits the [[Sun]] in a very elliptical orbit, moving retrograde to the Sun, unlike the planets which move prograde, or counter-clockwise looking from the north of the [[Solar System]]. [[periapsis|Periapsis]] takes Halley to between the orbits of [[Mercury]] and [[Venus]], and at [[apoapsis]] it is beyond that of [[Neptune]].

===Orbiter 2002-P1, with subsequent patches===
 
−
Author's Comments:<br>
 
−
Orbiter's second release in 2002, which then included three subsequent revisions as patches to the base 021202 install.
 
  
−
These are cumulative, which means if you want 030303 you need to unpack the 021202 base, then the 021206 patch, the 021217 patch, and then finally the 030303 patch, to get a working install.
+
Note that when landed on Halley near the apoapsis, Halley provides only about 1% of the total gravity, the other 99% by the Sun, but, near apoapsis, Halley provides 98% of the gravity, the Sun, only about 2%. It may be difficult to stay landed near Halley's periapsis. The sphere of influence near apoapsis is about 37 km from the center, and near periapsis, the SOI is right about the surface.
  
−
You'll need both _base and _tex for a working 021202 base install.
+
It can be difficult to visit Halley as when it is near apoapsis, Halley is traveling at about 900 m/s, but it's 35 AU from the Sun. Near Periapsis, it's about 0.5 AU from the Sun, but it's traveling almost 55000 m/s.

The second revision of Orbiter from 2003. While this wasn't called 2003-P1 at the time as far as I can tell, that's what Orbiter later started using, so I've kept that format here as we go backwards in time.

Halley's Comet, also referred to as 1P/Halley, is a short period comet appearing in the skies every 72 to 80 years, last seen in 1986 and the next will be in 2061. Named after Edmond Halley who was the first to recognize it as a recurring comet although it has been seen since ancient times.

Halley in Orbiter[edit]

Halley was introduced to Orbiter as an add-on in 2004. Since Orbiter was not designed to show a comet's tails, the add-on depicts it as a rugby ball shaped body much like an asteroid. Halley orbits the Sun in a very elliptical orbit, moving retrograde to the Sun, unlike the planets which move prograde, or counter-clockwise looking from the north of the Solar System. Periapsis takes Halley to between the orbits of Mercury and Venus, and at apoapsis it is beyond that of Neptune.

Note that when landed on Halley near the apoapsis, Halley provides only about 1% of the total gravity, the other 99% by the Sun, but, near apoapsis, Halley provides 98% of the gravity, the Sun, only about 2%. It may be difficult to stay landed near Halley's periapsis. The sphere of influence near apoapsis is about 37 km from the center, and near periapsis, the SOI is right about the surface.

It can be difficult to visit Halley as when it is near apoapsis, Halley is traveling at about 900 m/s, but it's 35 AU from the Sun. Near Periapsis, it's about 0.5 AU from the Sun, but it's traveling almost 55000 m/s.

It should also be noted that when landing on Halley that the visual surfaces are well below the hard radius (5500 meters), which is not visible, so instrument landing with HUD in surface is recommended.
