1 dzień temu · One astronomical unit (about 150 million kilometres; 93 million miles) is defined as the mean distance between the centres of the Sun and the Earth. The instantaneous distance varies by about ± 2.5 million km or 1.55 million miles as Earth moves from perihelion on ~ January 3rd to aphelion on ~ July 4th. [36]
3 dni temu · Jupiter is the only planet whose barycentre with the Sun lies outside the volume of the Sun, though by only 7% of the Sun's radius. The average distance between Jupiter and the Sun is 778 million km (5.2 AU) and it completes an orbit every 11.86 years.
3 dni temu · Mercury has the most eccentric orbit of all the planets in the Solar System; its eccentricity is 0.21 with its distance from the Sun ranging from 46,000,000 to 70,000,000 km (29,000,000 to 43,000,000 mi). It takes 87.969 Earth days to complete an orbit.

2 dni temu · Jupiter, the most massive planet in the solar system and the fifth in distance from the Sun. It is one of the brightest objects in the night sky; only the Moon, Venus, and sometimes Mars are more brilliant. Jupiter takes nearly 12 Earth years to orbit the Sun, and it rotates once about every 10 hours.

Our planet Earth follows an elliptical orbit around the Sun, a path that defines the length of a year on our home planet. ... it is about 94.5 million miles (152 million kilometers) away. This variation in distance contributes to slight changes in solar radiation received by Earth, although this effect is minor ...
