Why Venus is the hottest planet and not Mercury?
Why is Venus the hottest planet in our solar system? Even though Mercury is the closest planet to the Sun, Venus is the hottest planet in our solar system. This is because Mercury has almost no atmosphere, while Venus has a very thick atmosphere. This causes all the heat to be radiated back into space on Mercury.
Why is Venus hotter than Mercury in answer choices?
Even though Mercury is closer to the Sun, Venus is the hottest planet in our solar system. Its thick atmosphere is full of the greenhouse gas carbon dioxide, and it has clouds of sulfuric acid. It’s so hot on Venus, the metal lead would melt.
Why does Venus have the hottest surface?
Venus is so hot because it is surrounded by a very thick atmosphere which is about 100 times more massive than our atmosphere here on Earth. As sunlight passes through the atmosphere, it heats up the surface of Venus. The heat becomes trapped and builds up to extremely high temperatures.
How hot is Venus surface?
900 degrees F.
It appears that the surface temperature ranges from about 820 degrees to nearly 900 degrees F. The average surface temperature is 847 degrees F., hot enough to melt lead. No wonder the ocean basins are “dry”.
How hot is Mercury surface?
800 degrees Fahrenheit
Mercury has almost no atmosphere. Because it is so close to the sun, it can be very hot. On its sunny side, Mercury can reach a scorching 800 degrees Fahrenheit!
Why is Mercury not the hottest planet?
Because it is so close to the sun, it can be very hot. On its sunny side, Mercury can reach a scorching 800 degrees Fahrenheit! (But Mercury is not the hottest planet in the solar system. On its dark side, Mercury gets very cold because it has almost no atmosphere to hold in heat and keep the surface warm.
Why is Mercury not the hottest?
Why is Mercury the hottest planet?
Mercury’s low mass and proximity to the sun keep it from having anything but the thinnest of atmospheres, and this is the reason it must pass on being the hottest planet. An atmosphere helps to cloak a planet, keeping heat from leaking into space.
Which is hotter Venus or the sun?
Venus is the second planet from the sun and has a temperature that is maintained at 462 degrees Celsius, no matter where you go on the planet. It is the hottest planet in the solar system. This thick atmosphere makes the surface of Venus hotter because the heat doesn’t escape back into space.
Is Mars hotter than Mercury?
Mars is reddish color and some people might have guessed that Mars is the hottest planet in the solar system. But just because it’s red, doesn’t make it the hottest. Mercury is the planet that is closest to the sun and therefore gets more direct heat, but even it isn’t the hottest.
Why is Mercury the second hottest?
Since Mercury lacks an atmosphere, it has no way of trapping the heat that is generated by the sun, thus leading it to have periods of both hot and cold. Though it isn’t the hottest planet, it is still comes in a respectable second place, even without an atmosphere.
Which is hotter the surface of Venus or mercury?
Because of the Greenhouse Effect on Venus, the surface temperature is regulated by the trapped infrared energy which cannot escape back into space to balance what it receives from the Sun as is the case for Mercury. This means that the surface temperature of Venus is far hotter than on Mercury, in the neighborhood of 472 C ( 882 F).
Why is the atmosphere of Venus so thick?
On the other hand, Venus has a thick atmosphere that traps the heat coming from the Sun. In fact, this planet has the thickest atmosphere in all terrestrial planets of the Solar System. Temperature averages at 462 degrees Celsius. It is also important to note that the atmosphere of Venus is composed mostly of carbon dioxide—a greenhouse gas.
Why does the surface of mercury not have an atmosphere?
Mercury actually lacks an atmosphere. The surface facing the Sun experience a maximum temperature of 425 degrees Celsius while the opposite surface cools down to -193 degrees Celsius. The lack of atmosphere allows radiation or heat to escape from the planet, thus cooling it down at night.
How is the surface temperature of mercury regulated?
The surface temperature of Mercury is completely regulated by its closeness to the Sun and is about 430 C ( 806 F) at local Noon. Because of the Greenhouse Effect on Venus, the surface temperature is regulated by the trapped infrared energy which cannot escape back into space to balance what it receives from the Sun as is the case for Mercury.
