SOLAR SYSTEM

Detailed explanation-1: -Neptune-the eighth and most distant major planet orbiting our Sun-is dark, cold and whipped by supersonic winds. It was the first planet located through mathematical calculations.

Detailed explanation-2: -Because its orbit is elliptical, its distance from the Sun changes depending on where it is in its orbit. The closest Neptune gets to the Sun is 2, 771, 087, 000 miles or 4, 459, 630, 000 kilometers.

Detailed explanation-3: -Answer: Pluto is usually farthest from the Sun. However, its orbit “crosses” inside of Neptune’s orbit for 20 years out of every 248 years. Pluto last crossed inside Neptune’s orbit on February 7, 1979, and temporarily became the 8th planet from the Sun.
