2021 July 08 - Perihelion to Aphelion
Channel: APOD Podcast
Date: 2021-07-08

In today's image, we see two images of our Sun. One was taken in January when the Sun was at its closest distance (perihelion) and appeared a bit larger. The other was taken in July when the Sun was at its greatest distance (aphelion) and appears slightly smaller.
