What is the temperature range on the planet Mercury?

Mercury has the greatest range of surface temperatures of any planet in the solar system. It ranges from about -300°F (-184°C) on the side away from the sun to about 800°F (427°C), at one or more points on the side currently facing sunward. There is no appreciable atmosphere to moderate the temperature extremes. As the planet slowly rotates (once about every 59 Earth days) the sun-heated surface reaches the "dark" side and can radiate heat into space. Craters near the poles have perpetually "cold" spots deep within them.

The time any location spends in either heat or cold is actually 88 days, because this comparatively slow spin and short orbital time increases the "solar day" to 176 days.

The average temperature for Planet Mercury is 179 °C.

How long does it take light to travel 4000 miles?

The speed of light is 186,000 miles per second, so divide 4000 by that figure. It's roughly .02 seconds, about 20 milliseconds.

How does mercury outboard 60 hp e60elcia work?

An E60ELCIA is not a Mercury. It is an Evinrude. A 1981 Evinrude.

And it works just like any other 2-stroke outboard engine.

What is Mercury's albedo?

Mercury's overall albedo is only about 10 per cent. It's surface, therefore, must be made of a dark material. Though a few regions are very reflective, with albedoes of up to 45 per cent.

Why is roman god of speed an appropriate name for the planet mercury?

Because it's the fastest to rotate around the sun than any other planet.

Would you feel heavier or lighter on mercury?

lighter

Earth is the densest planet in the Solar System and the most massive of all of the solid planets. You would be lighter on any planet except for gas giants.

How much would a 100g weight weigh on mercury?

Considering that grams are a unit of mass, their mass would still be 100g. If you used a unit of weight, such as pounds, the relative weight of an object would change from planet to planet. On Mercury, a person who weighed 100 lbs normally would instead weigh 38 lbs.

How far away from Mercury from earth?

Mercury is about 60 million miles away from the Earth.

Improved answer:

This distance may be roughly correct at some times, but

obviously it varies as the planets orbit the Sun. It's not possible to give a

simple numerical answer.

What is the coldest inner planet mercury or mars?

Depends: Mercury has the lowest overall temperatures as night on the planet can reach -173C (-279F). However day time temperatures at the equator reach 426C (800F). Also, a full rotation on Mercury is 58.6 Earth days. Parts of Mercury's polar regions are never exposed to the sun and reach temps below -171C (-276F) during the entire Mercurial day.

For absolute coldest temperatures reached: Mercury wins.

For mean equatorial temperatures:

Mars: -63C (-81F)

Mercury: 67C (152F)

For mean temperatures: Mars wins

Can you jump higher on mercury than on earth?

yes because of less gravity

How many moons does the planet Mercury have?

Mercury does not have any moons.

It was once believed that a moon might exist, based on radiation levels. However. it was later discovered to be the star 31 Crateris.

The nearness of Mercury to the massive gravity influence of the Sun is the likely reason that no natural satellites are present, although it is possible that one or more may have existed in the past.

How big is Mercury?

Mercury has a radius of 2,439 km or 1,515 miles, only about 38% the size of Earth.

It has a mass of 3.3022 × 1023 kg which is only 5.5% that of Earth (about 1/18th).

The diameter of Mercury is 4,879 km (3,031 miles), making it the smallest major planet in our solar system, smaller than the moons Ganymede (Jupiter) and Titan (Saturn). However, its higher density gives it a greater mass than these moons.
