About once every 248 years, Pluto moves nearer to the sun than Neptune, and stays that way for about 20 years. This last happened between January 1979 and February 1999 and so it won't happen again until about 2227.

Pluto does not actually cross Neptune's orbit as it does not orbit in the same plane. That said, Pluto's orbit does sometimes bring it close to the sun. Pluto last crossed this distance, moving away from the sun, on February 11, 1999. It will pass closer again in the year 2278.

The orbit of Pluto is sometimes closer to the Sun than Neptune's orbit. But, mainly due to the angles of their orbits, they never pass through the same point in space.

Neptune and Pluto switch every 248 years, but they only switch for a small amount of time.

Because Pluto's orbit crosses into Neptune's path and Neptune crosses Pluto's path.
