# Distance

The Distance of an object is the difference between the object's position and some reference point, defined by the Relative to property. In terms of vector mathematics, the Distance is the magnitude of the object's Position Vector.

## Property Details

### Location

The Distance property for an object can be found near the top of the Motion tab. For Galaxy objects, the Distance property is located in the Properties section of the Galaxy tab, and refers specifically to the Black Hole's Distance. For Galaxy Nebula objects, the Distance property is located in the Motion section of the Nebula tab.

The Distance property can be expanded to show the object's Position Vector.

### Units

Distance can be viewed and edited using the following units:

• Milky Way Galaxy radius (milky way) = 5.5×104 light year
• Parsec (parsec) = 3.08568025×1016 m
• Light-year (light year) = 9.46073047×1015 m
• Astronomical Unit (AU) = 1.495978707×1011 m
• Solar radius (sun) = 6.955×108 m
• Lunar distance (lunar dist) = 3.844×108 m
• Light-second (light sec) = 2.99792458×108 m
• Jupiter radius (jupiter) = 6.9911×107 m
• Earth radius (earth) = 6.37101×106 m
• Moon radius (moon) = 1.7371×106 m
• Kilometer (km) = 1000 m
• Meter (m) is the SI base unit for length
• Centimeter (cm) = 0.01 m
• Millimeter (mm) = 0.001 m
