For things to go truly wrong for the solar system, you’d only need the average distance between Neptune and the Sun ... the closest point on a planet’s orbit around the Sun – of Mercury ...

With Pluto spending 20 years of its 248-year orbit ... Neptune makes around the Sun, Pluto orbits twice. If they start getting out of sync, their mutual gravitational pull nudges them back into ...

Researchers have found that if a star flying past our solar system moved Neptune’s orbit by just 0.1 per cent, it would result in pandemonium. A minor shift in the outer planet’s orbit could ...

Distance from the Sun: Neptune is the eighth planet from the Sun. It orbits at an average distance of 2.8 billion miles (4.5 billion km), thirty times farther than Earth.Orbit around the Sun ...

Those moons, called S/2002 N5 and S/2021 N1, bring the total of Neptune’s known moons to 18. The moon S/2021 N1 takes about 27 Earth years to complete an orbit around Neptune while S/2002 N5 ...
