A planet is a celestial body that is in orbit around the Sun, has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes ahydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.

<h2>Answer: Neptune </h2>

The dwarf planet Pluton, has the most eccentric orbit (more elliptical and elongated) of all the planets, and as a consequence its orbit is "intersected" by the orbit of Neptune.

However, despite this intersection, there is no collision risk between these two bodies, since the orbit of Pluto is located in an orbital plane different from that of the other planets and therefore different from that of Neptune, its nearest neighbor. In addition, the orbit of Pluton is inclined $17\°$ on the the ecliptic plane (plane where the other planets move around the Sun).
