When a superior planet is 180 degrees from the sun?
A superior planet is at opposition when it is on the opposite of the Earth to the Sun (elongation = 180 degrees).
What is the synodic period of Venus in years?
Synodic and Sidereal Periods of the planets
| Planet | Synodic Period (days) | Sidereal Period |
|---|---|---|
| Venus | 584 | 225 days |
| Earth | – | 1.0 year |
| Mars | 780 | 1.9 years |
| Jupiter | 399 | 11.9 years |
What is the synodic period of Mars in years?
2.135 years
What is the best configuration for observing a superior planet?
An elongation of 0 degrees and the planet positioned on the same side of the sun as Earth is called opposition. This is the best time to observe a superior planet. The superior planets appear to behave different from Mercury and Venus when seen from Earth.
In which configuration will a superior planet be visible all night?
Because a superior planet never can pass between the Sun and the Earth, superior planets are always seen at nearly full phase. They will never be seen as a crescent or new.
Why superior conjunction is a poor choice for measuring the synodic period of an inferior planet?
The superior planets that are farther from earth with bigger orbits will have faster synodic periods because the observer’s planet will be able to go around its orbit faster. Therefore, it will take less time for the synodic period.
What are the true colors of the planets?
