How could I calculate the alignment of 3 planets that orbit around the sun at the same speed? I have this data:
- P1: Distance from the sun 1000km and angular velocity 1 degree per day.
- P2: Distance from the sun 5000km and angular velocity 3 degree per day.
- P3: Distance from the sun 9000km and angular velocity 5 degree per day.
What about if need to know if they alignment to sun too?
