'''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'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.

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 was introduced to [[Orbiter]] as an add-on in 2004.

| − | + | 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. | |
