How would one calculate the synodic period of the Earth and an elliptical orbit?
For example, when would someone with a telescope be able to see Starman and his Roadster (when will the Tesla roadster's elliptical orbit cross ours again, and how would that be calculated?)
For two ...

Determining effect of small variable force on planetary perihelion precession
Is there an analytical technique for determining the effect of a small variable transverse acceleration upon the rate of aspides precession (strictly not a precession but rotation of the line of ...

What is the difference between barycentric-centered and heliocentric-centered coordinates?
When talking about celestial bodies orbiting the sun with a decently circular orbit or small aphelion, the heliocentric orbital parameters are almost identical to the barycentric parameters. However, ...

In the early solar system, were most orbits highly eccentric?
I'm wondering why all the planet orbits are circular when it seems to me they should almost all be eccentric.
Obviously, it's because that's the only stable orbit. But in those very early times when ...

Does the Giant Impact Hypothesis explain how the Moon circularized its orbit?
I just read most of Wikipedia's article on the Giant Impact Hypothesis. Basically a large object impacts Earth and creates debris that soon coalesces into the Moon.
But there is something I did not ...

Why do planets move in an elliptical orbit? [duplicate]
I am a student of class 9 and recently came to know about kepler's law of planetary motion and got confused about the foci and elliptical orbits of planets and some stars.

Can the Moon provide momentum to an object in Earth's orbit? Gravity Assisted Boost [closed]
Can a satellite maintain an equatorial orbit around Earth near the Moon's orbit to receive partial gravitational boosts by gaining momentum as the satellite passes though the Moon's gravity well?
I'...

What maintains the high orbital eccentricity of many exo-planets near their sun?
Over the last decade we've discovered that many exoplanets not only have highly eccentric orbits, but also orbit very close to their sun. This is true of many classes of stars.
I definitely have a ...

How does 'centre of mass' concept work?
We know that two celestial bodies rotate around a center of mass. How does this concept work in case of solar systems where there are several planets versus one/two stars? (Even if the center of mass ...
