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.)
What else can I help you with?
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.
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.
Which element has chemical properties most similar to those of the element calcium?
atoms in the same group are similar. calcium is in group 2, so it's similar to Be, Mg, Sr, Ba and Ra. Most similar would be Mg or Sr, which are right above and below. all group 2 atoms share a similar electron configuration
What are all the planets that have planets?
A planet can not have planets.it probably can have planets say somehow 2 planets crashed together then exploded and little pieces come from the planet
The largest planets of your solar system are found between which 2 planets?
mars and uranus
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.
What 2 planets have the most circular orbits?
venus and pluto
What 2 planets have most circular orbits?
venus and pluto
What 2 outer planets are similar in size?
Uranus and Neptune are similar in size, with Uranus having a diameter only 1.5% larger than that of Neptune. Both planets are classified as ice giants and are part of the outer solar system.
4 inner planets?
The four inner planets are Mercury, Venus, Earth, and Mars. These planets are referred to as terrestrial planets because they are rocky and similar in composition. They are also located closer to the sun compared to the outer planets.
What 2 planets are most likely to have conditions that could support life?
Mars and Venus
What are the 2 kinds of planets?
Rocky planets and gaseous planets.
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.
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.
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.
In which two groups are the elements most similar in their chemical properties?
1 and 2
How are outer planets diffrent from inner planets?
The Inner Planets (Mercury, Venus. Earth, and Mars) have many differences between the Outer Planets (Jupiter, Saturn, Uranus, and Neptune), some of the main ones as follows: • All the Inner Planets are terrestrial planets, while the Outer Planets are gaseous planets. • Comparably, the Outer Planets are much bigger than the Inner Planets. • Mars, the Inner Planet with the most moons has no more than 2 moons. However, each of the Outer Planets have at the very least 10 moons each. • The Outer Planets have much longer orbital periods than the Inner Planets, due to the fact that they're further away from the Sun. • Venus, the Inner Planet second closest to the Sun, has extremely hot temperature conditions (an average of 870 F or 450 C), but the Outer Planets have very cold weather, all in negative degrees of at least -240 F or -150 C. Also, Venus is the hottest planet, and Uranus is the coldest one.
