1. Planets in the orbits all conform to Kepler's three laws of planetary motion, 2. The orbits are all nearly in the same plane,
3. The orbits are all elliptical, but not very ellptical and near-circular in shape, with the Sun slightly off-centre.
Added:
p2 = a3
P. The planetary orbital period in earth years.
a. Distance from sun in astronomical units, based on 1 AU for earth. ( for example, Mars would be about 1.5 AU and you would use this value in the equation, not the actual distance )
All the planets have orbits so four cannot be picked out.
ALL closed gravitational orbits are ellipses.
orbits of the planets.
As an elliptical orbit is any orbit that isn't perfectly circular, everything has an elliptical orbit. The planets Mercury and Pluto have the most elliptical orbits of the planets, and are easily seen to be oval shaped. Comets also have highly elliptical orbits.
That could be one of the "terrestrial" planets, but most likely the required answer is "asteroid".
Venus has the least eccentric (most nearly circular) orbit of the eight in our solar system.
All the planets have orbits so four cannot be picked out.
ALL closed gravitational orbits are ellipses.
Most cross orbits of planets which allows it to hit the planets easier. They do not go into a full orbit at all.
