When at "perihelion" (the orbital point where a planet is closest to the Sun), Mercury is about 46.0 million km from the Sun and at "aphelion" (the orbital point farthest from the Sun), it is at a distance of 69.8 million km.
What is the aphelion of Venus?
Venus's 225-day orbit around the Sun will carry it to its furthest point to the Sun – its aphelion – at a distance of 0.73 AU. In practice, however, Venus's orbit is very close to circular; its distance from the Sun varies by only about 1.5% between perihelion and aphelion.
What is Mercury’s aphelion distance?
0.47 AU Mercury's 88-day orbit around the Sun will carry it to its furthest point to the Sun – its aphelion – at a distance of 0.47 AU.
What is the aphelion of Saturn?
At its farthest (aphelion), Saturn hovers 934 million miles (1.5 billion km) from the sun; at its closest (perihelion), the distance to Saturn from the sun is "only" 839 million miles (1.4 billion km). Such a distance means that Saturn's temperature remains chilly year-round.
What is the aphelion of Mars?
According to a NASA fact sheet, due to Mars' eccentric orbit, at its closest (perihelion) Mars is about 128 million miles (206 million km) from the sun and at its farthest distance (aphelion) Mars is about 154 million miles (249 million km) from the sun.

What is the gravity in Mercury?
3.7 m/s²Mercury / Gravity Gravity on Mercury: This makes Mercury the smallest and least massive planet in the solar system. However, thanks to its high density – a robust 5.427 g/cm3, which is just slightly lower than Earth's 5.514 g/cm3 – Mercury has a surface gravity of 3.7 m/s2, which is the equivalent of 0.38 g.

What is the aphelion of Uranus?
Uranus travels in an elliptical orbit around the sun once every 84 Earth years. At its closest (perihelion), the distance to Uranus from the star is 1.7 billion miles (2.5 billion km); at its farthest (aphelion), 1.89 billion miles (3 billion km).
