The world known as Terra Nova ("New Land" or "New Earth", from Terran Portuguese, Catalan and Latin) was settled just over 1900 cycles ago (in AD 4752), helped by the discovery of the Tannhauser Gates and the advent of Gateships.


Located approximately 1.5 million kilometers closer to its star, Helios, than Earth is to its own sun and having only a 3° axial tilt, Terra Nova is a world that runs slightly warmer and with less fluctuation in temperature than the original home of humanity. Indeed, temperatures only fluctuate on the average of 4 degrees Celsius between the seasons of Summer and Winter.

The entire world is primarily covered in land mass, and while once geologically active it is now quite settled into its current state. The only truly active tectonic activity is that located from the volcanoes in the Western Desert that form the Great White Desert's acidic white sand. Beyond that, much of the planet's water supply runs underneath the planet's surface through the MacAllen Tunnel System, which is rumored to be capable of linking both the northern and southern hemispheres across the barren equatorial desert areas of the Badlands, although this has never been fully confirmed.

The planet rotates on its axis every 37.2 Terran hours, while its entire orbit around Helios is 168.2 local days (260.7 Terran days). To help the original colonists deal with the time changes, each Terranovan hour was made to be 62 minutes long (where Terranovan minutes and seconds are equal to their Terran counterparts), a Terranovan day was made to be 36 hours long, and a Terranovan week is seven days long (where the days are named identically to those in a Terran week). The Terranovan "cycle" - the equivalent of a Terran year - was made to be 168 days long (with a leap day known as the Interannum being added every five cycles) and was divided into four seasons (Winter, Spring, Summer and Autumn) of six weeks apiece; Terranovan calendars have no equivalent of the Terran "month". Terranovan dates follow a "day, season, and cycle" format, where Day 1 of cycle 1 in the Terranovan calendar coincides with April 3, 4752 on Earth's Gregorian calendar & the first local winter solstice after Terra Nova's discovery & colonization; as with Earth's calendar, there is no "year zero" in the Terranovan calendar. Likewise, January 1, AD 6132 (which may also be expressed as "1 January AD 6132") on Earth's calendar would coincide with 10 Winter TN 1933 on Terranova's calendar.

Terra Nova is orbited by three moons: Hope, Faith, and Charity. Hope is a large body similar to Earth's Moon & completes an orbit once every 24 Terranovan days, while Faith & Charity are smaller bodies that are more similar to Mars' moons (Phobos & Deimos).
