For a typical $95,000 railcar, a high investment grade company might see 12-year lease rates of $475 per car per month for 12 years, while a low investment grade might see $575 per car per month for eight years. Total cost may be from the 2.50% I just mentioned to a higher rate of 4.25%.
We can't land here on Jupiter's surface, since it's a sea of cloud tops, but we can get warmer by descending. Buffeted by extreme winds, we descend, and the pressure mounts. The winds don't subside. They continue to blow about 450 mph (725 km/h) all the way down the atmosphere (at least as far as we've probed).
What we see when looking at these planets is the tops of clouds high in their atmospheres (slightly above the 1 atmosphere level). Jupiter is about 90% hydrogen and 10% helium (by numbers of atoms, 75/25% by mass) with traces of methane, water, ammonia and rock. This is very close to the composition of the primordial Solar Nebula from which the entire solar system was formed.
