each planet's orbit is shaped like an ellipse. Predict whether the shapes of the planet's orbits will be more circular or more elongated.

If modified, orbits will be more elongated instead o circular because the effect on them will be an orbital increased drag.

Explanation:

To understand this phenomenon, we need to understand the context. First of all, only a major event in the orbit will cause it to change. Because they can last until the star becomes a nebula and then absorbs the bodies that orbit it. Thus, if modified by a strong factor or event. The orbit will become more elongated because the event will make the planet or object lose it for a moment and push it farther from its regular orbit. This will cause a variance in it and it will drag the planet until it crashes with the star or greater object due to the variance and the elongated new orbit.
