The temperature of Jupiter’s core is 24,000 degrees Celsius (43,232 degrees Fahrenheit), which is hotter than the surface of the sun. Consequently, the gas giant displays a larger temperature gradient from surface to core than any other planet.
Which planet has the greatest difference between night and day temperatures?
Mercury: Planet Closest to the Sun
It is smaller than any other planet. Mercury is very close to the Sun and has no substantial atmosphere. 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.
What planet is very hot in daytime and very cold at night?
(But Mercury is not the hottest planet in the solar system. The hottest planet is Venus.) On its dark side, Mercury gets very cold because it has almost no atmosphere to hold in heat and keep the surface warm. The temperature can drop down to minus 300 degrees Fahrenheit.
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 |
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.
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 planet is closest to the sun?
Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon. Mercury is the fastest planet, zipping around the Sun every 88 Earth days.
Which is the coldest planet of our solar system?
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).
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).
What is the slowest planet?
Venus, which is floating higher each evening in twilight, low in the west, is the slowest-spinning body in the known universe.
What planet is the darkest?
Kepler has found the darkest known planet in universe–a Jupiter-sized exoplanet some 750 light-years away that is so black that it reflects just one percent of the light that reaches it. TrES-2b is so black that it’s darker than coal, or any other planet or moon that we’ve yet discovered.
Is Saturn hot or cold?
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.
Which planet has longest day?
Option 2: A Table
| Planet | Day Length |
|---|---|
| Venus | 5,832 hours |
| Earth | 24 hours |
| Mars | 25 hours |
| Jupiter | 10 hours |
Why is Mars so hot?
In orbit, Mars is about 50 million miles farther away from the Sun than Earth. That means it gets a lot less light and heat to keep it warm. Mars also has a hard time holding onto the heat it does get. On Earth, much of the sun’s heat gets trapped in our atmosphere, which acts like a blanket to keep our planet warm.
What is the current temperature on Mars?
Surface temperatures may reach a high of about 20 °C (293 K; 68 °F) at noon, at the equator, and a low of about −153 °C (120 K; −243 °F) at the poles. Actual temperature measurements at the Viking landers’ site range from −17.2 °C (256.0 K; 1.0 °F) to −107 °C (166 K; −161 °F).
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.
