Explanation

Neptune is the eighth and farthest planet from the Sun in our solar system.

It takes approximately 165 Earth years to complete one orbit around the Sun.

• Neptune: ~165 Earth years
• Uranus: ~84 Earth years
• Saturn: ~29.5 Earth years
• Jupiter: ~12 Earth years
• Mars: ~687 Earth days (1.88 years)
• Earth: 365.25 days
• Venus: ~225 Earth days
• Mercury: ~88 Earth days 

Explanation

• Venus comes closest to Earth when it is between Earth and the Sun.

• Minimum distance: about 24 million miles (≈ 38 million km).

• This close approach occurs roughly every 584 days.

Additional Information:

• Mercury can be about 33 million miles away when Venus is on the far side of the Sun.

Explanation

Jupiter has the shortest day of any planet in our solar system

It completes one rotation in approximately 9 hours and 56 minutes.

It is also the fastest-spinning planet in the solar system.

Explanation

The coldest planet in our solar system is Uranus,

They hold the record for the lowest temperature ever measured at -371°F (-224°C)

It has 27 moons.

Its largest moon is Titania.

ADDITIONAL INFORMATION 

Neptune is also extremely cold, with an average temperature of -214°C (-353°F)

NOTE:  IF THE OPTION IS Pluto, Saturn, Mars, Jupiter ( Pluto is the correct answer)

Pluto, which is no longer classified as a planet (it is a dwarf planet), is the coldest of all the large bodies in the outer solar system,

has a temperature of about -225°C (-373°F).

NOTE: IF THE OPTION IS Uranus, Neptune, Venus, Pluto ( Uranus is the correct answer)

According to most sources, the coldest planet in the Solar System is Neptune.

Explanation

Explanation

Heat from the Sun reaches Earth through radiation

It is the transfer of energy via electromagnetic waves (like infrared, visible light, UV) 

Sunlight takes an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.

Explanation

Light from Sun travels a distance of  150 Million km before it reaches Earth

Distance: ~93 million miles (150 million km) on average.

Speed of Light: ~186,282 miles/second (300,000 km/s) in a vacuum.

Travel Time: Approximately 8 minutes, 20 seconds (or 500 seconds).
