These factors contribute to the fact that the surface of Mercury has the greatest temperature range of any planet or natural satellite in our solar system. The surface temperature on the side of Mercury closest to the Sun reaches 427 degrees Celsius, a temperature hot enough to melt tin.
Which planet has the greatest daily temperature change?
Highs and lows. Orbiting between 28 and 43 million miles (46 and 70 million kilometers) from the sun, Mercury, also the smallest planet, feels the brunt of the solar rays. According to NASA, the tiny world suffers the most extreme temperature range of any other planet in the solar system.
Which planet has the highest temperature?
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.
Which planet has the greatest fluctuation difference between high and low in temperature?
Due to the tenuous atmosphere, Mercury really has no weather to speak of other than wild fluctuations in temperature. In fact, Mercury has the largest diurnal temperature spread of any planet in our solar system. This is explained by a few factors.
Which planet has the largest temperature difference between day and night?
Venus. Mercury has the largest day-night temperature difference.
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.
Is Venus hot or cold?
The average temperature on Venus is 864 degrees Fahrenheit (462 degrees Celsius). Temperature changes slightly traveling through the atmosphere, growing cooler farther away from the surface. Lead would melt on the surface of the planet, where the temperature is around 872 F (467 C).
Which is the hottest and coldest planet?
Shakeel Anwar
| Name of Planets (Hottest to Coldest) | Mean Temperature (Degree Celsius) |
|---|---|
| 1. Venus | 464 |
| 2. Mercury | 167 |
| 3. Earth | 15 |
| 4. Mars | -65 |
Is the sun a planet?
The Sun is a yellow dwarf star, a hot ball of glowing gases at the heart of our solar system. Its gravity holds the solar system together, keeping everything – from the biggest planets to the smallest particles of debris – in its orbit.
Which 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 coldest inner planet?
With a temperature of -357 degrees Fahrenheit, Uranus is the coldest planet in the solar system.
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.
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.
Which planet has the shortest day?
The planet Jupiter has the shortest day of all the eight major planets in the Solar System. It spins around on its axis once every 9 hr 55 min 29.69 sec. Jupiter has a small axial tilt of only 3.13 degrees, meaning it has little seasonal variation during its 11.86-year-long orbit of the Sun.
How many planets are in the universe 2020?
For those of you who like to see gigantic numbers written out in full, around 10,000,000,000,000,000,000,000,000 planets in our observable Universe, and that’s only counting planets that are orbiting stars.
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.
