Surface liquids indicate that there can be a gaseous atmosphere, as surface liquids and volatile ices are heated. Liquid hydrocarbons such as ethane show a very cold planet. Liquid sulfur shows a very hot interior. Liquid water shows a warm temperature, an indicator of possible lifeforms (on the surface or in the interior, under an ice shell).
First quarter and third quarter phases of the moon produce the least variation in the tides.
Back when Pluto was still listed as a planet it was considered to have the weakest gravity of all the solar system's planets. Now that Pluto has been demoted from planetary status, the planet with the weakest surface gravity is Mercury. While Pluto's gravity is weaker than that of any planet in the solar system, there are still many non-plantery objects with weaker surface gravity.
The hottest (surface temperature) is Venus then, getting colder: Mercury, Earth, Mars, Jupiter, Saturn, Neptune and Uranus. (In fact Neptune and Uranus are very similar in temperature.)

Pluto. It is the 9th planet from the sun and it is very different then Earth in size and temperature
Neptune is the most unknown since it's far away
Lakes usually have the least variation in salinity.
According to Oklahoma Edition of McDougal Littell Science Grade 7 the Terrestrial Planet that has the oldest least changing surface is Mercury. Mars has wind that carries sand that changes its surface. Venus has volcanoes and tectonic plates that change its surface. We know that Earth has erosion, volcanoes and tectonic plates that change the surface. This leaves Mercury.
~mountains... well thatz a start... forgot the other 2...
All places that are on the Equator have the least variation in the length of daylight hours.
Yes, The surface temperature of Mercury ranges between 100 K and 700 K. while that on Venus (caused by the greenhouse effect of it atmosphere) is at least 735 K.
Since sound waves are a compression and rarefaction in the atmosphere, the planet with the least atmosphere (most like a vacuum) would be least likely to have audible sounds on its surface. In our solar system Mercury stands out as the best candidate here since it has almost no atmosphere.
