solar system quick facts by metric scalemodes

The following datasheets, compiled and presented by AAT with information from recent science resources, can be downloaded at no charge.

Each scalemode references metric units; however measures of time and angle are scaled in terms of different dials. scalemode-SI scales time by the second and angular measure by the degree. scalemode-SI-UT1 scales time by both the second and its day-multiple-equivalent, with angular measure also scaled by the degree. scalemode-SI-ICAS scales time by a day-multiple-equivalent for which a decimal submultiple that is exactly 0.864 s is designated, and for which angular measure is scaled rather by the grad.

In each scalemode, measures for objects in the solar system are compared to measures for the planet Earth. The comparison unit for each feature is thus the known magnitude of that feature for the planet Earth. As such the measures of Earth-comparison are the same for each scalemode.
