What is Tritons density?
To find out, we need to know how to compute a density. Then we compute • The density of water is 1000 kg/m3. • The density of rock is 3000 kg/m3 more or less. • The density of the moon is 3300 kg/m3. • We could conclude that the moon is mostly made of rock. • The density of the earth is about 5500 kg/m3. • That tells us that the rock in the middle of the earth is compressed, making it more dense. • It also tells us that there is a lot of iron in the middle of the earth. • Triton is less dense than the moon. • We conclude that Triton is made of rock and ice. Temperature: 37 K (that’s on the Kelvin scale.) • That’s cold.
