What are the temperatures of all the planets?
The mean temperatures of planets in our solar system are:
- Mercury – 333°F (167°C)
- Venus – 867°F (464°C)
- Earth – 59°F (15°C)
- Mars – Minus 85°F (-65°C)
- Jupiter – Minus 166°F (-110°C)
- Saturn – Minus 220°F (-140°C)
- Uranus – Minus 320°F (-195°C)
- Neptune – Minus 330°F (-200°C)
What is the order of the planets from hottest to coldest?
Hottest and Coldest Planet in the Solar System
| Name of Planets (Hottest to Coldest) | Mean Temperature (Degree Celsius) |
|---|---|
| 1. Venus | 471°C |
| 2. Mercury | (430°C) during the day, (-180°C) at night |
| 3. Earth | 16°C |
| 4. Mars | -28°C |
How do we know the temperature of other planets?
The temperature can be inferred by what materials haven’t frozen out of the atmosphere yet, which can be determined with spectroscopy. Typically, the first one is done, and the second when a more accurate method cannot be used (IE, no direct spectrum of the planet observed).
What is the warmest planet in our solar system?
Venus
Venus’ thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.
Why do planets vary in temperature?
The factors that determine the temperature are a complex balance between the amount of heat received and that lost. The heat received by a planet varies with its distance from the Sun, for it is the Sun’s radiation which is by far the greatest source of planetary warming.
What is the coldest temperature on Venus?
Surface temperatures of the inner rocky planets
| Mercury | – 275 °F (- 170°C) | + 840 °F (+ 449°C) |
| Venus | + 870 °F (+ 465°C) | + 870 °F (+ 465°C) |
| Earth | – 129 °F (- 89°C) | + 136 °F (+ 58°C) |
| Moon | – 280 °F (- 173°C) | + 260 °F (+ 127°C) |
| Mars | – 195 °F (- 125°C) | + 70 °F (+ 20°C) |
Is Saturn hotter or colder than Earth?
With an average temperature of minus 288 degrees Fahrenheit (minus 178 degrees Celsius), Saturn is a pretty cool planet. Although there are some small differences as one travels from the equator to the poles, much of Saturn’s temperature variation is horizontal.
What temperature is just right for a planet to become habitable?
Life seems limited to a temperature range of minus 15oC to 115oC. In this range, liquid water can still exist under certain conditions. At about 125oC, protein and carbohydrate molecules and genetic material (e.g., DNA and RNA) start to break apart. Also, high temperatures quickly evaporate water.
How cold is it on Mercury?
It is understood that the sunny side may reach temperatures of 750 to 800 degrees F., while the nighttime temperature plummets to nearly -330 degrees F. The average temperature on Mercury is a balmy 354 degrees F.
What planets has the highest average temperature?
The planet with the highest average surface temperature is Venus, because of its thick atmosphere and its proximity to the sun. The average temperature on the surface of Venus is 860 degrees Fahrenheit. Venus is the second closest planet to the sun; the closest planet to the sun is Mercury.
What planet has the greatest variation in temperatures?
Venus is the hottest planet in the Solar System. Neptune has the coldest average temperature in the Solar System. Despite being coldest to the sun, Mercury is actually cooler than Venus due to its slow rotation and thin atmosphere. When compared to the average temperature on Earth, the other planets can clearly be seen to be far outside our understanding of life supporting temperature ranges.
What is the normal temperature of all the planets?
Temperature of the Planets and the Sun. Temperature of the Planets and the Sun. Rank Name Temperature (Kelvin) 1: Sun: 5778: 2: Venus: 737: 3: Mercury: 440: 4: Moon >100 to 400: 5: Earth: 288: 6: Mars: 210: 7: You can use our temperature converter to carry out the conversions of temperature.

What factors affect the temperature of all planets?
The radiated power of the star per unit area of the planet – 1370W/m2 for the earth at 1au from the Sun.
