Planetary surface temperatures tend to get colder the farther a planet is from the Sun. Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet.
Which planet has the highest average surface temperature and why?
Venus: That honor goes to Venus, the second closest planet to the Sun which also has the highest average surface temperatures – reaching up to 460 °C on a regular basis.
What is the surface temperature of the planets from highest to lowest?
Surface temperatures of the inner rocky planets
| Planet | Minimum surface temperature °F (°C) | Maximum surface temperature (°F (°C) |
| 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) |
Why does Venus have the highest surface temperature?
Atmosphere. Venus’ atmosphere consists mainly of carbon dioxide, with clouds of sulfuric acid droplets. The thick atmosphere traps the Sun’s heat, resulting in surface temperatures higher than 880 degrees Fahrenheit (470 degrees Celsius).
Which planet has the largest temperature difference between day and night?
Venus. Mercury has the largest day-night temperature difference.
Why is Venus called Earth’s sister?
Venus is a terrestrial planet and is sometimes called Earth’s “sister planet” because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects.
What planet is the coldest?
Neptune, being the eighth planet in our solar system and therefore the one furthest from the sun, has the coldest average temperature (around -214°C).
Which planet is hottest and coldest?
Shakeel Anwar
| Name of Planets (Hottest to Coldest) | Mean Temperature (Degree Celsius) |
|---|---|
| 1. Venus | 464 |
| 2. Mercury | 167 |
| 3. Earth | 15 |
| 4. Mars | -65 |
What is the closest planet to the sun?
The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth’s Moon.
Which inner planet has the longest year?
Given its distance from the Sun, Neptune has the longest orbital period of any planet in the Solar System. As such, a year on Neptune is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days).
What is the temperature on Venus at night?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
How close is Venus to Earth today?
The distance of Venus from Earth is currently 257,817,325 kilometers, equivalent to 1.723402 Astronomical Units. Light takes 14 minutes and 19.9860 seconds to travel from Venus and arrive to us.
Why is Venus hot and Mars cold?
We’ve learned that Venus is too hot because it has a runaway Greenhouse effect, caused by a broken carbon cycle, from too little water; Mars is too cold because its carbon cycle is also broken, lacking active volcanoes, and therefore it has too small a Greenhouse effect.
What planet is known as Earth’s twin?
Venus is Earth’s evil twin — and space agencies can no longer resist its pull. Once a water-rich Eden, the hellish planet could reveal how to find habitable worlds around distant stars.
What is the hottest temperature on Mercury?
Mercury is hot. If we’re being quantitative, it’s actually extremely hot! As the closest planet to the Sun, it completes an orbit in just 88 Earth-days, achieving a maximum temperature during the day of a whopping 700 Kelvin (427 °C / 800 °F) at its hottest, equatorial locations.
Why Venus is hottest planet than Mercury?
The carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.
