The Aphelion and Perihelion are just "apoapsis" and "periapsis" of the Sun. Similarly, the "apoapsis" and "periapsis" of Earth are called "apogee" and "perigee". So, the two seperate articles are pointless.

Well, if the sites are cross-referenced and linked, I see no reason to change. In fact, the perihelion entry could be made more detailed. Strictly speaking it's the barycentre (of the Earth and the Moon) that is at perihelion, so the centre of the Earth isn't always closest to the sun at perihelion, it might be closer on other days close by (unless it's a full moon). And because of apsidal precession - the Earth rotating on its axis - and taking into account precession of the Earth's axis the direction of perihelion will change, so that in around 6,000 years perihelion will occur in mid-March rather than in January.— Preceding unsigned comment added by 184.108.40.206 (talk • contribs) 00:12, 12 March 2021 (UTC)
