Data File Updated: Saturday, May 11, 2019

Here are some reference materials to aid with the visualization and perspective of the scales of objects and locations in Outsider. I plan to add as many diagrams and illustrations to this section as I can over time.

Useful Units of Measurement

Speed of light (in vacuum) = 299,792,458 meters per second
1 Light Second (LS) = 299,792 kilometers
1 Light Minute (LM) = 17,987,548 kilometers
1 Light Year (LY) = 9.46 x 1012 kilometers
1 Parsec (Pc) = 3.26 light years
1 Astronomical Unit (AU) = 149,597,870.691 kilometers (8.3 LM)
1 Earth day = 86,400 seconds
1 Earth (tropical) year in 2000 A.D. = 365 days, 5 h, 48 m, 45 s (31,556,925 s)
1 Earth gravity (g) = 9.80665 m/s2
1 Newton (N) = 1 kg*m/s2
1 joule (J) = 1 Newton*meter

Conversions

1 mile = 5,280 ft = 1.6093 km
1 inch = 2.54 cm
1 foot = 0.3048 m
1 pound = .4536 kg
1 ounce = 28.35 g
1 kg = 2.2046 lbs.
1 knot = 1.151 mph = 1.852 km/h
1 gallon = 3.7853 liters
1 ton (short) = 2,000 pounds = 907.18 kg
1 metric ton = 1,000 kg = 1.102 short tons
1 Newton = 0.2248 pounds

Orbital Platform* (any) (any) <1 ? Mepona Station

*System Defense craft are spacecraft with no jump drive and only minimal propulsion, so the "max thrust" value is usually <5g.

Planetary Environment


Note: The sizes of the Earth and Moon in (Fig.V) are to scale with the distances between them. The ship icons are not to scale.

Exosphere Altitude: 300 km
Low Earth Orbit (LEO) Altitude: 300-800 km
International Space Station Altitude: ~350 km
Hubble Space Telescope Altitude: ~560 km		 Geostationary Orbit (GEO): Altitude 35,786 km (orbital radius 42,164 km)
Chandra X-ray Observatory Max Altitude: ~126,000 km (orbital apogee ~133,000 km)
Maximum Beam Weapon Range: ~300,000 km (~1 Light Second)
Earth-Moon Lagrange-1 Orbital Radius: 326,000 km (58,400 km from the Moon)

Moon Diameter: 3,476 km
Moon Surface Gravity: 0.17g

Solar System


Note: The sizes of the Sun and the planets in (Fig.VI) are NOT to scale, but the distances are. The jump zone indicates appropriate distance from the Sun (4-5 AU) but not location; the Alpha Centauri jump zone is well below the plane of the planets.
