C/1861 G1 (Thatcher) (source of the April Lyrids) is expected to come to perihelion. [64] 2284 Perihelion of Comet Halley. [65] Previous perihelion passages were in 1986, 2061, 2134, and 2209. 2287 C/1979 Y1 (Bradfield) (suspected source of the July Pegasids) is expected to come to perihelion. [66] 2287 August 28
Perihelion currently occurs around 3 January, so the Earth's greater velocity shortens winter and autumn in the northern hemisphere, and summer and spring in the southern hemisphere. Summer in the northern hemisphere is 4.66 days longer than winter, and spring is 2.9 days longer than autumn. [ 14 ]
At perihelion, Earth is roughly 91.4 million miles away from the sun. On average, the planet is separated from the sun by a distance of approximately 93 million miles.
The six Earth images are positions along the orbital ellipse, which are sequentially the perihelion (periapsis—nearest point to the Sun) on anywhere from January 2 to January 5, the point of March equinox on March 19, 20, or 21, the point of June solstice on June 20, 21, or 22, the aphelion (apoapsis—the farthest point from the Sun) on ...
The current perihelion, near January 4, is fairly close to the solstice of December 21 or 22. ... Kepler's life is summarized on pp. 523–627 and Book Five of his ...
This means that over a period of 18.2 inex cycles (526 years) the date moves around the whole year. But because the perihelion of Earth's orbit is slowly moving as well, the inex series that are now producing tetrads will again be halfway between Earth's perihelion and aphelion in about 586 years.

From perihelion to aphelion, the size of the Sun increases almost 66%, as does the brightness. This is due to the high eccentricity of Mercury's orbit around the Sun. [ 1 ] A 19th century depiction of the apparent size of the Sun as seen from the Solar System's planets (incl. 72 Feronia and the then most outlying known asteroid, here called ...
