Basic Examples  (4)

Use for discovery:

Find the orbit period of a minor planet:

Get a list of classes of minor planets:

Find the planets in a given class:

Scope  (3)

Date qualifiers can accept an explicit DateObject or queries that evaluate to a DateObject:

Date qualifiers can also be specified using Dated:

Location qualifiers can accept an explicit GeoPosition, location-based Entity objects, or queries that evaluate to one of these:

The Hilda group of minor planets has orbital periods that are approximately 2/3 of Jupiter's. Adding a bit of uncertainty to this value and plotting their positions with respect to Jupiter and the Sun shows they are found along a nearly triangular region:

Applications  (1)

Query for the orbital semimajor axis for asteroids in the asteroid belt:

The Kirkwood gaps are the result of orbital resonances with Jupiter:

Possible Issues  (1)

Pluto is not included in the list of solar system planets:

It is now considered a "dwarf planet":

Neat Examples  (4)

Create a histogram of the distances of Apollo asteroids from the Sun:

Plot orbit period versus orbit semimajor axis for a group of minor planets:
