Time it takes to circle and astrological chart (360° in circumference), which also equals the planet's orbit around the sun |
Planet: |
Time: |
Sun: |
365 Earth days and spends approx. 30 days in each sign |
Moon: |
27 days and 7 hours and spends 2.3 to 2.5 days in each sign |
Mercury: |
88 Earth daysmoves around the chart approx. 4 times each year and spends about 7.5 days in each sign (not including retrograde periods). |
Venus: |
225 Earth days and spends approx. 18.7 days in each sign (not including retrograde periods). |
Mars: |
687 Earth days or 1.9 years (almost two years) and spends approx. 57.3 days in each sign (not including retrograde periods). |
Retrograde Periods |
Sun: |
None |
Moon: |
None |
Mercury: |
Three times per year for 3 weeks per retrograde period |
Venus: |
Retrogrades every 18 months for approx. 40 days |
Mars: |
Retrogrades every 26 months for 10 weeks (70 days) |
Number of Satellites (Moons and Asteroids) |
Sun: |
|
Moon: |
None, though she does go "void" as she moves from sign to sign. A void period can last from a few minutes to two days |
Mercury: |
None |
Venus: |
None |
Mars: |
Two moons, Phobos and Deimos (diameter of fourteen miles and seven miles, respectively). |
Degrees This Planet Moves on Average Per Day |
Sun: |
Approx. 1° |
Moon: |
Approx. .5° per hour, or 12° per day. |
Mercury: |
Approx 4° per day |
Venus: |
Approx. 1.6° per day |
Mars: |
Approx. .5° per day, which would be a movement of 30 minutes |
Consistency |
Sun: |
Star ball of incandescent gas of average size and brightness compared to other stars. |
Moon: |
No air and no liquid water. No weather. Landforms are a result of meteoric impact. |
Mercury: |
Less than half the diameter of Earth. No air or water. |
Venus: |
Covered in bright clouds of sulfuric acid. Atmospheric pressure is 90 times that of Earth. Most of the surface is covered by undulating plains. |
Mars: |
Has a 24-hour day, a pattern of seasons, and polar ice caps. Temperatures on Mars rarely rise above freezing. Called the red planet because it is covered by red deserts. Some think Mars is the precursor of Earth and was destroyed by war. |
