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) |
Which planet has a very hot surface?
Similar in structure and size to Earth, Venus spins slowly in the opposite direction from most planets. Its thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system with surface temperatures hot enough to melt lead.
Which planet has the highest average surface temperature and why quizlet?
It is a thousand times more massive than all the planets combined. Where does nuclear fusion occur in the Sun? Which planet has the highest average surface temperature, and why? Mercury.
Which planet has much higher average temperature and why?
The reason Venus is hotter than even Mercury is not because of its position in the solar system but because of its thick, dense cloud layer. Venus is the planet most similar to the Earth in terms of size and mass, but its atmosphere causes huge differences in the temperatures of the two planets.

What is the hottest thing in the universe?
The hottest object in the Universe, literally speaking, is the Big Bang. If we go back in time, the Universe gets denser and hotter without a limit. The Big Bang singularity marks the breakdown of Einstein’s theory of gravity, where the density and temperature of matter and radiation diverge to infinite values.
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.
How close is Venus to Earth today?
The distance of Venus from Earth is currently 257,825,833 kilometers, equivalent to 1.723459 Astronomical Units. Light takes 14 minutes and 20.0144 seconds to travel from Venus and arrive to us.
What is the temperature of Saturn?
Like the other gas giants, Saturn’s surface to atmosphere interface is rather nebulous, and likely has a small, rocky core surrounded by a liquid and very thick atmosphere. Saturn is considerably colder than Jupiter being further from the Sun, with an average temperature of about -285 degrees F.
What planet is the closest size to Earth?
Venus is similar in size to Earth, which earned it the title of Earth’s twin. Venus has a diameter of 12,100 km and a surface area of 4.6 x 108 km2. These measurements are 95% and 90% of Earth’s diameter and surface area respectively. With a volume of 9.38 x 1011 km3, Venus’ volume is 86% of Earth’s.
Will Pluto eventually collide with Neptune?
Since Pluto and Neptune cross orbits, is it possible that the two planets will collide? No, they actually can’t collide because Pluto’s orbit takes it much higher above the Sun’s orbital plane. When Pluto is at the same point as Neptune’s orbit, it actually much higher up than Neptune.
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).
Why is Saturn so hot?
Summary: New analysis of data from NASA’s Cassini spacecraft found that electric currents, triggered by interactions between solar winds and charged particles from Saturn’s moons, spark the auroras and heat the planet’s upper atmosphere.
Why is Jupiter so hot?
It’s really hot inside Jupiter! No one knows exactly how hot, but scientists think it could be about 43,000°F (24,000°C) near Jupiter’s center, or core. Jupiter is made up almost entirely of hydrogen and helium. … These changes happen because of the tremendous temperatures and pressures found at the core.
