1.24 billion miles.
Callisto is approximately 1.8 billion kilometers away from Earth.
2 billion miles = 3,218,688,000 km
The farthest Neptune gets from the sun is about 2.819 billion miles (4.537 billion kilometers.)
The voyager 2 was 14676939366306 meter away from earth as of 5 July 2012 (00:00 GMT).
Pluto is about 5,913 million km far from the sun (on average). Earth is about 150 million km far from the sun. Earth is about 5,763 million km far from Pluto. BUT PLUTO IS NOT PLANET ANYMORE
Neputune is approx. 4.503 billion kilometers away from the sun
if you mean Uranus it can be from 2.57 billion km (2 570 000 000 kilometers) to 3.15 billion km (3 150 000 000 kilometers) since it rotates around the sun and could be ether from the closest to the furthest point of their orbit 1 Mile = 1.609344 Kilometers
2 billion miles3 218 688 000 kilometers == The formula used to arrive at the answer:2 billion mi*1.609344 km1 mi=3.2 billion km
Voyager 2 was launched on Aug. 20, 1977. Voyager 1 was launched on Sept. 5, 1977. On March 7, Voyager 1 was 17.4 billion kilometers (10.8 billion miles) away from the sun. Voyager 2 was 14.2 billion kilometers (8.8 billion miles) away from the sun, on a different trajectory. To my knowledge these are objects are the farthest man made creations from our star.
It extends from roughly 4.4 to 7.4 billion kilometers from the Sun.
4.4 billion kilometers is 4,400 million kilometers.
Saturn is, on average, about 886 million miles (1.43 billion kilometers) away from the Sun. This distance can vary due to the elliptical shape of its orbit, ranging from approximately 746 million miles (1.20 billion kilometers) at its closest (perihelion) to about 925 million miles (1.49 billion kilometers) at its farthest (aphelion).
