Using instruments aboard the Japanese lunar orbiter SELENE (also known as Kaguya), Takaaki Tanaka and his team from the Tokyo Institute of Technology, made the first spacecraft-based observations of the lunar exosphere when the Moon was inside Earth's magnetosphere.
From the measurements of water in the exosphere, the researchers calculated that the hydrated layer has a water concentration of about 200 to 500 parts per million, or about 0.02 to 0.05 percent by weight.
When solar wind particles slam into Mercury's surface, they knock atoms from surface rocks and into Mercury's tenuous exosphere. It's not a proper atmosphere--individual atoms rarely encounter each other, so it has no wind or weather--and spacecraft like Messenger and BepiColombo can fly directly through it unimpeded, tasting atoms that until recently were part of the planet's surface.

Ionosphere layer is one part of the upper atmosphere comprising portions of the mesosphere, thermosphere, and exosphere. Generally, ionosphere varies with the activity levels of the Sun, time, geographical position, and so on.
