Comparison of the Sun with Earth at perihelion (closest to the Sun) on January 5, 2020, versus the Sun with Earth near aphelion (farthest from the Sun) on July 8, 2021. This shows the slight difference in the size of the Sun's disk due to Earth's changing distance from the Sun through the year. Earth was 152,100,527 kilometres (km) from the Sun on the actual day of aphelion, July 5, and 147,091,144 km from the Sun on January 5. On January 5, 2020 the Earth was at its closest perihelion of the 21st century, making for the largest solar disk of the century, and a 'supersun'.
