Why the orbits of planets are elliptical and not circular?
That's interesting, but can a planet's orbit change over time?
Yes, a planet's orbit can change over time due to a number of factors, including gravitational influence from other planets, changes in the planet's own mass distribution, and even the effects of solar flares and other astronomical events. In some cases, these changes can be significant enough to cause a planet to move into a different part of the solar system altogether.
