"Perihelion" is a place in space, not on the earth. It's the point in the orbit of any
member of the solar system where the orbiting object is closest to the sun.
Earth reaches its perihelion each year during the first few days of January. In 2010,
it was in the 7 PM hour EST on January 2.
No. The "sub-solar" point is that point on the Earth where the Sun is STRAIGHT UP from there.
You probably meant Perihelion. Perihelion is the closest point to the sun of a planet or other solar objects.
The Subsolar Point is the shortest distance between the Earth and Sun. The distance constantly changes, because of orbits, drifts, shifts, tilts, etc. However, by definition, the subsolar point is the point on the Earth's surface where the Sun is at its highest (or lowest) latitude at local solar noon. Subsolar points change daily moving from 23.5° South to 23.5° North (the solstices) and back throughout the year. To the extent that the subsolar point is directly beneath the sun (i.e., when the sun's rays are exactly perpendicular to the Earth's surface), it would also be true that the closest point on Earth to the sun at that particular point in time would be the subsolar point. NOTE: The shortest distance between two bodies forms a perpendicular line between the closest parallel planes of both bodies. Subsolar point is the term used to identify the point on a planet which is closest to the sun at any given moment.
Subsolar PointBy definition, the subsolar point is the point on the Earth's surface at which the Sun is at its highest (or lowest) latitude at local solar noon. The Subsolar point changes continually as the Earth rotates and seasonally moving from 23.5 degrees South to 23.5 degrees North (the solstices) and back throughout the year. To the extent that the subsolar point is directly beneath the sun (i.e., when the sun's rays are exactly perpendicular to the Earth's surface), it would also be true that the closest point on Earth to the sun at that particular point in time would be the subsolar point.
The closest point to the Sun in a planet's orbit is called perihelion. The furthest point is called aphelion. Phil
Solar PointI don't know. I know what the subsolar point is, it's the point in a orbit (of an object around a planet) where the sun is as close to overhead as it can get. Am I close? if this is true then the solar point would most likely be noon on earth. or at scale (since he said a satelite to the sun) it could be when the center of the galaxy is closest to overhead earth of course that could be the galactic point. im not really sure either.
The subsolar point.
Earth reaches the point in its orbit called 'perihelion' early in January.
