What planet has the largest day/night temperature difference?
Which planet has the largest day-night temperature difference? A. Mercury B. Earth C. Uranus D. Venus. Mercury has the largest day-night temperature difference.
What planet has the highest variation in temperature in our solar system?
Mercury is the planet that is closest to the sun and therefore gets more direct heat, but even it isn’t the hottest. 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.
Which planet experiences the widest range of temperatures?
Answer and Explanation: The planet Venus experiences the smallest range of temperature of any planet in our solar system. Its surface stays at about 890 degrees Fahrenheit at all times.
How is Mercury not the hottest planet?
(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.
What planet has the most extreme temperatures?
Without an atmosphere, Mercury loses a great deal of heat into space, rather than sharing with its night side. The hottest planet, incidentally, is Venus, the second body from the sun. Venus has a thick atmosphere that blankets the planet, keeping its temperature at an average of 864 F (462 C).
How hot is Jupiter day and night?
Jupiter’s orbit around the sun is elliptical, or oval-shaped. Jupiter takes 12 Earth years to make one revolution around the sun, so one year on Jupiter is equal to 12 years on Earth. The temperature in the clouds of Jupiter is about minus 145 degrees Celsius (minus 234 degrees Fahrenheit).
What is the highest temperature ever recorded on Uranus?
Uranus is the coldest planet in our Solar System, with a lowest recorded temperature of -224°C. Despite its distance from the Sun, the largest contributing factor to its frigid nature has to do with its core.
Which is the hottest and coldest planet?
The Hottest And Coldest Planets Of Our Solar System
- Venus. Venus is the second planet from the sun and the hottest in the solar system.
- Mercury. Mercury is the first and smallest planet in the solar system.
- Pluto. Pluto is a dwarf planet made of ice and rock.
- Neptune.
Why is it cold in space when you are closer to the sun?
Answer 3: At higher altitudes, the air is thinner. Without this atmosphere, Earth would be uninhabitably cold. So, even though higher altitude areas are closer to the sun, they have less ability to absorb the warmth of the sun because they have less of these gases.
Why is Mercury very hot during the day and very cold at night?
It is very hot during the day (over 400°C) because Mercury is so close to the Sun. At night it is very cold because Mercury loses almost all its heat since there is almost no atmosphere to keep the warmth there. The temperature can fall to almost -175°C.
What is Mercury’s temperature at night?
Since Mercury is the closest planet to the Sun, spins slowly, and does not have much of an atmosphere to trap heat, its temperature varies greatly. Mercury’s temperatures can go between -279 Fahrenheit (-173 Celsius) at night to 801 Fahrenheit (427 Celsius) during the day. (This is hot enough to melt lead!)
Why is Mercury so cold at night?
Despite its proximity to our star, Mercury is not the hottest planet in the solar system. With no atmosphere to trap heat, surface temperatures on Mercury can swing from 800 degrees Fahrenheit during the day to -290 degrees Fahrenheit at night.
Is Mercury hotter than Earth?
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 is Mercury sky always black?
The Moon’s atmosphere is negligibly thin, essentially vacuum, so its sky is always black, as in the case of Mercury. However, the Sun is so bright that it is impossible to see stars during the daytime, unless the observer is well shielded from sunlight (direct or reflected from the ground).
Does Mercury have a moon?
Small planets tend to have few moons: Mars has two, Earth has one, while Venus and Mercury do not have any. Earth’s Moon is unusually large compared with the planet.
What is the biggest storm in the solar system?
Great Red Spot
Which planet has the largest volcano?
Mars
Why is Venus sometimes called Earth’s twin?
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.
Is Jupiter habitable?
Despite this, some scientists estimate that there are as many habitable exomoons as habitable exoplanets. Given the general planet-to-satellite(s) mass ratio of 10,000, large Saturn or Jupiter sized gas planets in the habitable zone are thought to be the best candidates to harbour Earth-like moons.
Who discovered Jupiter?
Galileo Galilei
Does Jupiter have an atmosphere?
The atmosphere of Jupiter is the largest planetary atmosphere in the Solar System. It is mostly made of molecular hydrogen and helium in roughly solar proportions; other chemical compounds are present only in small amounts and include methane, ammonia, hydrogen sulfide and water.
How far is the sun from Earth?
149.6 million km
Have we sent anything to the sun?
It became the first NASA spacecraft named after a living person, honoring physicist Eugene Parker, professor emeritus at the University of Chicago. The previous record, 26.55 million miles from the Sun’s surface, was set by the Helios 2 spacecraft in April 1976.
How bright is the sun?
-26.74
Is Mercury a planet?
Mercury is the smallest and innermost planet in the Solar System. Its orbital period around the Sun of 87.97 days is the shortest of all the planets in the Solar System. It is named after the Roman deity Mercury, the messenger of the gods.
What is the temperature of the sun?
5,778 K
Why hasnt Mercury been pulled into the sun?
Another reason why so few missions have targeted Mercury is that it is very difficult to obtain a satellite orbit around the planet on account of its proximity to the Sun, which causes the Sun’s gravitational field to pull on any satellite that would be set into Mercury’s orbit.
Why is the earth known as the blue planet?
Earth is the only planet in our solar system that has a large amount of liquid water. About 74% of the surface of Earth is covered by liquid or frozen water. Because of this, people sometimes call it “blue planet”.
What gas makes up most of the Martian atmosphere?
carbon dioxide
