If you consider both planets and dwarf planets, the two with the closest mean surface temperatures are Jupiter (165 K) and Ceres (168 K), and the second-closest are Pluto (44 K) and Eris (42.5 K). If considering only planets, the closest are Uranus (76 K) and Neptune (72K), and the second-closest are Mercury (270 K) and Earth (288 K).
To determine closeness of temperatures, rather than just calculating the difference between each pair I calculated the percent difference. The mean temperatures of Pluto and Eris are only 1.5 degrees apart compared to 3 degrees between Jupiter and Ceres. However, Pluto's temperature is 3.53% higher than Eris', whereas Ceres' temperature is only 1.82% higher than Jupiter's.
Before you assume I've gone space-happy for suggesting that Mercury and Earth have similar temperatures, understand that I used the average temperature of each whole planet. Earth's temperatures range from 184 K to 330 K, but Mercury's temperatures range from 80 K to 700 K.
Since the gas giants are giant balls of gas, when the phrase surface temperature is used with respect to them, it means the temperature of the atmosphere at the depth where the air pressure is the same as the air pressure at the surface of the earth.
(To convert from Kelvin (K) to Celcius (C), subtract 276.15.)

Which 2 planets is close to the same size?
Venus and Earth are similar in size, also Uranus and Neptune are pretty similar in size.
Which are the 2 coldest planets?
Uranus and Neptune have the coldest surface temperatures. Their average temperatures are very similar at about minus 200 to minus 220 degrees Celsius.
What is the difference between motion of electrons in an atom and the motion of planets in the solar system?
1. Electrons travel really fast at room temperature (at any temperature above absolute zero, which is unattainable in practice) 2. They take unpredictable orbits. 3. They don't orbit on the same plane like planets do. 4. Electrons bind to the nucleus with the electromagnetic force, which is different than planets, which are held to the sun by gravity.
How many dwaft planets are in your solarsystem?
there are 2 darft planets in the solar systems
Planet's axis of rotation is greatly lifted causing unusal seasons?
1. EARTH 2. MARS Most planets have rotation axes that are tilted away from being perpendicular to the plane in which they orbit the Sun. Seasonal variations are most pronounced on these two terrestrial (Earth-like; rocky) planets with moderate gaseous atmospheres.
What 2 outer planets are similar in size?
Venus and earth.

What 2 planets have the most circular orbits?
venus and pluto
Which 2 inner planets have the most craters?
Mercury and Mars.
What 2 planets have most circular orbits?
venus and pluto
What are the 2 kinds of planets?
Rocky planets and gaseous planets.
What 2 planets are most likely to have conditions that could support life?
Mars and Venus
What planets are most like your sun and how?
No planets will ever be like Sun. 1. Sun is star. 2. No matter how hot a planet is, they'll never be as hot.
Of the inner planets which contains the most number of moons?
Of the inner planets, Mars has the most moons. Mars has 2 moons compared the Earth having 1 moon and Venus and Mercury having none.
What are the 2 other name of inner planets?
Terrestrial Planets, and Rocky Planets
