Question

Which planet has the highest surface temperature ?

Answer 1

Hint: Before answering this question we will know about planets of our solar system, then we will know which planet has how much temperature and then by comparing it we will know which planet has the highest surface temperature.

Complete answer:
Mercury: The Mercury is the smallest and fastest planet, Mercury is the closest planet to the Sun and orbits around it every 88 Earth days. At daytime the temperature in Mercury is too high but at night it lowers down.
Venus: Venus spins in the opposite direction to most planets, Venus is the hottest and one among the brightest objects within the sky. Temperatures remain the same on Venus regardless of day or night.
Earth: Earth is the planet which we call home, Earth is the third rock from the sun and the only planet with known life on it.
Mars: Mars is a dusty red planet, cold world with a thin atmosphere.
Jupiter: Jupiter is a massive planet, twice the dimension of all other planets combined and features a centuries-old storm that is bigger than Earth.
Saturn: Saturn is the most recognizable planet with a system of icy rings, Saturn is a very unique and interesting planet.
Uranus: Uranus features a very unique rotation, it spins on its side at an almost 90-degree angle, unlike other planets.
Neptune: Neptune is the most distant planet and is a cold and dark nearly 3 billion miles from the Sun.

The temperature table is as below:

Planets	Temperature
Mercury	800°F (430°C) during the day, -290°F (-180°C) at night
Venus	880°F (471°C)
Earth	61°F (16°C)
Mars	minus 20°F (-28°C)
Jupiter	minus 162°F (-108°C)
Saturn	minus 218°F (-138°C)
Uranus	minus 320°F (-195°C)
Neptune	minus 331°F (-201°C)

Hence, Venus has the highest surface temperature.

Note:Though planetary temperatures rise with the proximity to the sun, Venus is actually warmer than its neighbour Mercury, for a few reasons. As we know, Mercury has a slow rotation period, meaning it differs drastically in temperature between its daylight and night time. Furthermore, it has a thin atmosphere which allows heat to escape. Whereas, Venus has a very dense atmosphere, which means it traps heat much like a greenhouse.
