Ellipses
One of the discoveries that led to the modern view of the Solar System was that the orbits of the planets were ellipses. This was one of the key contributions from Johannes Kepler's laws of planetary motion, which replaced the earlier belief that planetary orbits were perfect circles.
No, not all planets have elliptical orbits. While most planets in our solar system have nearly circular orbits, some planets, like Mercury and Pluto, have more elliptical orbits. Additionally, exoplanets outside our solar system can have a variety of orbital shapes.
The orbits of all planets in our solar system do not overlap; each planet has its own distinct orbit around the Sun. However, there are times when planets appear close together in the sky from our viewpoint on Earth due to their positions in their respective orbits.
No, the planets do not leave their orbits and their orbits do not cross
Planets are held in their orbits by the gravitational force exerted by the sun. This force is what allows planets to stay in motion around the sun without flying off into space or falling into the sun.

Gravity from the Sun holds the planets in their orbits.
The wording of this question needs to be improved to understand what you mean.
No, not all planets have elliptical orbits. While most planets in our solar system have nearly circular orbits, some planets, like Mercury and Pluto, have more elliptical orbits. Additionally, exoplanets outside our solar system can have a variety of orbital shapes.
The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.
None of the planets pass out of our solar system. The orbits of the planets, irregular as they may be IS the solar system.
That was the work of Kepler, resulting in his Laws of Planetary Motion.
All planets in our solar system have elliptical orbits.
It doesn't. All of the planets in our solar system orbits the sun.
Yes, none of the planets in our solar system have exactly circular orbits, though some are more eccentric than others.
The planets and other objects in the solar system stay in their orbits due to the mutual gravitational attraction between each orbiting object and the Sun.
The orbits of all planets in our solar system do not overlap; each planet has its own distinct orbit around the Sun. However, there are times when planets appear close together in the sky from our viewpoint on Earth due to their positions in their respective orbits.
