This is really two separate questions, see the related questions links for the two temperatures.
Neptune is colder than Mars. Neptune is the eighth planet from the sun and is much farther from it compared to Mars, which is the fourth planet from the sun. Neptune's average temperature is around -353°F (-214°C), while Mars's average temperature is around -80°F (-62°C).
No, Mars is not hotter than Neptune. Neptune, being a gas giant, is much colder than Mars, which is a rocky planet. Neptune's average temperature is around -360°F (-218°C), while Mars has an average temperature of about -80°F (-62°C).
Temperature relies on distance from the Sun. In order the planets are ... Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto So Mercury is hottest as it is closest to the Sun Mars is closer than Neptune, so is hotter. So Neptune is colder.
Yes, Neptune is larger than Mars. Neptune is the fourth largest planet in our solar system, while Mars is the fourth smallest. Neptune is nearly 4 times the diameter of Mars and is significantly more massive.
Pluto is actually colder than Neptune at 33K. Neptune's surface temp drops to 72K and Uranus' drops to 76K. While Neptune should be much colder, it is thought to have a very high internal temperature.
The hottest (surface temperature) is Venus then, getting colder: Mercury, Earth, Mars, Jupiter, Saturn, Neptune and Uranus. (In fact Neptune and Uranus are very similar in temperature.)
Neptune is much colder than Mars.
They go like this: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune They go like this: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune

Neptune > Earth > Mars > Mercury Largest ---> Smallest
Neptune takes longer to orbit the sun than Mars. Neptune's orbital period is about 165 Earth years, while Mars' orbital period is about 1.88 Earth years.
