Explanation:

According to Kepler's first law, the orbit of a planet is an ellipse with the Sun at one of the two foci. For Mercury's elongated (more elliptical) orbit, the Sun is at a focus that is relatively far from the center of the ellipse, creating a more stretched - out position relative to the center of the orbit. For Neptune's more circular orbit, the two foci of the ellipse are very close to the center (since a circle is a special case of an ellipse where the two foci coincide at the center). So the Sun, being at one of the foci, is very close to the center of Neptune's nearly - circular orbit. In comparison, the Sun in Mercury's orbit is offset from the center of the orbit (towards one end of the major axis of the ellipse) to a greater extent than in Neptune's orbit.

Answer:

In Mercury's elongated (elliptical) orbit, the Sun is at one of the foci of the ellipse, which is significantly offset from the center of the orbit (along the major axis of the ellipse). In Neptune's more circular orbit, the Sun (at one of the foci of the elliptical orbit) is very close to the center of the orbit (since a circle is an ellipse with coinciding foci at the center). So the Sun is more offset from the center of Mercury's orbit compared to its position (near the center) in Neptune's orbit.
