2020 January 09 - Perihelion to Aphelion
Channel: APOD Podcast
Date: 2020-01-09

In today's image, we see two images of the Sun taken six months apart. The left side was taken a few days ago, near perihelion so that the Sun appears slightly larger. The right side taken six months ago near aphelion appears slightly smaller. This is caused by the changing distance between the Earth and Sun due to the Earth's elliptical orbit. This changing distance does not affect the seasons which are cause by the Earth's tilt on its axis.
