Would the temperature of a planet without an atmosphere be cooler than a planet with one?

That would depend on the planet's proximity to the star (sun) around which it revolves, and the type of atmosphere. In our solar system, atmospheres on solid planets retain and distribute heat, and on gas giants create heat.
Examples of Atmospheric Effects
On Mercury, the lack of an atmosphere means that one side is hellishly hot, while the other side (out of sunlight) is incredibly cold. An actual atmosphere, if it existed, would likely transport heat from one side to the other.
On Venus, the composition of the atmosphere (CO2 with high clouds of sulfuric acid) traps the Sun's heat and makes it scorchingly hot on the entire planet.
On the Earth, our atmosphere blocks the most intense solar radiation, and transports heat energy to colder regions. But insufficient solar radiation still allows very cold places such as Siberia and Antarctica.
On Mars, the lower solar radiation and the thin atmosphere make it colder than it would be with a thicker atmosphere, or clouds like Venus. Unfortunately, Mars is too small to hold much of an atmosphere.
On the outer gas giant planets, most of their volume is atmosphere, and the pressure makes them hotter deep inside, even without much heat from the Sun (in any case, sunlight could never be seen from their hidden solid surface).

∙ 15y agoThe atmosphere is responsible for trapping and radiating energy. It heats our earth. Without it, the average temperature would most certainly drop. Compare the earth to the moon in this respect, they're approximately the same distance from the sun, and although you can tinker with the moon's albedo compared to that of the earth, the moon's avg. temperature is still far far lower than that of current earth. And earth would probably drop even lower than that of the moon, considering it absorbs less solar energy per unit area than the moon.

Should tyhe atmosphere porvit uneven heating of eath?
Yes, the atmosphere should provide uneven heating of the Earth. This is because it is essential for the planet's climate to remain relatively stable. The different temperatures in different regions of the Earth are necessary for the preservation of life forms, as some species and ecosystems require different temperature ranges to thrive. Without the atmosphere, the planet would be subject to drastic changes in temperature over any given area. The atmosphere helps to regulate temperatures by:Trapping heat from the sun and radiating it back to the Earth.Redirecting winds, which carry cooler air to warm areas and warmer air to cooler areas.Absorbing and reflecting certain wavelengths of light, which can help to cool or warm the Earth's surface.The atmosphere's uneven heating of the Earth is an important part of its climate regulation. Without it, temperatures would be much more extreme and unpredictable, making it difficult for life to exist on the planet.
How does the temperature of the planets vary with distance from the sun?
The further a planet is from the sun, the less light and heat radiation it gets from the sun leaving it a cooler planet. However, a planet with a gaseous atmosphere is less likely to radiate away the planets heat so it may retain more of the solar heat.
What planet looks more like earth in temperature gravity atmosphere and water?
Mars is the planet most like Mother Earth.
Which planet has no true atmosphere?
Mercury. Its close orbit to the Sun causes extreme temperature variances and prevents it from maintaining any substantial gaseous atmosphere.
Does a planet need an atmosphere?
No. The planet Mercury does not have an atmosphere.
What planet is the highest temperature is our solar system?
Planet with an atmosphere, Venus. Planet without an atmosphere, Mercury (on the day side).
Which planet has no atmosphere what is the consequence of this?
Mercury has not atmosphere, resulting in extreme temperature variations.
What is greenhouse effect in planetary science?
That means that due to the presence of an atmosphere, and specific gases in the atmosphere, the average temperature on the planet is higher than it would have without an atmosphere - or without specific gases. Greenhouse gases, that increase the average temperature, include carbon dioxide (CO2) and methane (CH4).
Which planet atmosphere is increased by the greenhouse effect?
Research has shown that the planet Venus has its atmosphere temperature increased by the greenhouse effect
Which planet has no atmosphere and the day time temperature is 700K?
Mercury

Could you ever live on the planet mars?
Without a suit? No, the planet's atmosphere is thin and without oxygen.
How does the temperature of the planets vary with the distance from the sun?
The further a planet is from the sun, the less light and heat radiation it gets from the sun leaving it a cooler planet. However, a planet with a gaseous atmosphere is less likely to radiate away the planets heat so it may retain more of the solar heat.

What planet has extreme temperature because it has no atmosphere?
Jupiter(: <----WRONG! It is Mercury.
What planet is cooler Saturn or Jupiter?
Jupiter. Saturn's core is around 11000oC which drops down to around -150oC in its atmosphere. Jupiter's lowest temperature is around 30oK (only slightly above absolute zero).
How is the planet's distance related to its temperature?
The farther a planet is from the sun, the cooler it is, except that this is not true about Mercury and Venus. Also, the farther a planet is from other planets, the cooler it is, except that this is not true about Mercury and Venus. The distance that a planet is from comets, asteroids, other stars besides the Sun, meteoroids, or major league baseball teams has no effect on their temperature.
