What is the point in an orbit closest to the Sun called? The point closest to the Sun is called perihelion.

Perihelion combines Greek roots meaning “near” and “Sun.” It is the closest point in an orbit around the Sun, while aphelion is the farthest point. Together, these are the two apsides of a heliocentric orbit. The broader term periapsis means the closest point to the central body, regardless of what that body is.

An orbit’s distance from the Sun changes when it is elliptical rather than perfectly circular. At perihelion, an orbiting object moves fastest under Kepler’s second law, sweeping out equal areas in equal times. Earth reaches perihelion in early January, even though the Northern Hemisphere is experiencing winter; seasons are caused mainly by Earth’s axial tilt, not its changing distance from the Sun.

Perihelion is easily confused with perigee. Perigee is the closest point to Earth, whereas aphelion is the Sun-related opposite of perihelion. For an orbit around Earth, the corresponding farthest-point term is apogee.
