Maybe. no one knows. They have been like they are for thousands of years. But maybe in the future they could for whatever reason.
Elliptical orbits of the planets around the sun actually match what we observe. Newton's Theory of Universal Gravitation states that planets will move around the sun in elliptical orbits.

i do not this answer that's why i am asking you this answer.
elliptical
If the planets did not move in their fixed orbits they may dash each other.
Orbits help a planet move because of gravitational pull which makes the planet orbit round and round. The planets orbit around the son and the moon orbits around earth. Hope this helps!
Johannes Kepler was the first to state that planets move in elliptical orbits.

closer to the sun
All the planets have elliptical orbits but Uranus and Neptune have slightly different orbits than other planets on solar system.
The planets move intheir ellipticalorbits becauseof the gravitation of the Sun combined withthe inertial velocity of the planets(tangentialto their orbital paths). Mathematics shows the resulting orbits must be ellipses. (Some of the ellipses are in factalmost circles.)
