Diurnal Movement
The Sun's Daily Motion often is used as Directional Key
The distance a planet moves within a 24 hour period. There can be considerable variation in this value for planets that have retrograde motion (Stationary Phase), especially in the case of the inner planets Mercury and Venus:
| Planet | Average | Maximum | Minimum[1] |
|---|---|---|---|
 Moon |
13° 10' 35" | 16° 30' 00" | 11° 45' 36" |
 Mercury |
1° 23' 00" | 2° 25' 00" | − 1° 30' 00" |
 Venus |
1° 12' 00" | 1° 22' 00" | − 0° 41' 12" |
 Sun |
59' 08" | 1° 03' 00" | 57' 10" |
 Mars |
31' 27" | 52' 00" | − 26' 12" |

4' 59" | 15' 40" | − 8' 50" |
 Saturn |
2' 01" | 8' 48" | − 5' 30" |

12' 40" | 30' 00" | − 16' 00" |
 Pallas |
12' 20" | 40' 30" | − 22' 30" |
 Juno |
14' 15" | 39' 00" | − 18' 00" |
