Jump map from Travellermap.com

Ulun Har is a vacuum world, which warrants hazardous environment precautions.

• Life in a vacuum requires great discipline. After all, it only takes one forgotten seal on a vacuum suit to spell death. Those who survive tend to be very methodically-minded and attentive to small detail.
• This world is a "Twilight Zone World", a planet that is tidally-locked to its star. It has a hot side that permanently faces the star, a cold side that permanently faces away, and a narrow twilight zone in-between.
• It is an unclaimed Non-Aligned world located in the Sithula Subsector of Divide Sector.
