Wikipedia
Subsolar point
The subsolar point on a planet is the point at which its sun is perceived to be directly overhead (at the zenith); that is, where the sun's rays strike the planet exactly perpendicular to its surface. It can also mean the point closest to the sun on an astronomical object, even though the sun might not be visible. To an observer on a planet with an orientation and rotation similar to those of Earth, the subsolar point will appear to move westward, completing one circuit around the globe each day, approximately moving along the equator. However, it will also move north and south between the tropics over the course of a year, so it is spiraling like a helix. The subsolar point contacts the Tropic of Cancer on the June solstice and the Tropic of Capricorn on the December solstice. The subsolar point crosses the Equator on the March and September equinoxes.

Subsolar point
The subsolar point on a planet is where its sun is perceived to be directly overhead, that is where the sun's rays are hitting the planet exactly perpendicular to its surface. It can also mean the point closest to the sun on an object in space, even though the sun might not be visible. For planets with an orientation and rotation similar to the Earth's, the subsolar point will move westward, circling the globe once a day, but it will also move north and south between the tropics over the course of a year. The December solstice occurs when the subsolar point is on the Tropic of Capricorn and the June solstice is at the instant when the subsolar point is on the Tropic of Cancer. The March equinoxes and September equinoxes occur when the subsolar point is on the equator. The subsolar point is frequently used in celestial navigation and the coordinates of the subsolar point at various times throughout the year can be found in a nautical almanac. When the point passes through Hawaii, it is known as Lahaina Noon.
