Recently discovered satellites
Recent advances in technology have enabled astronomers to detect extremely faint objects orbiting planets. Most of these objects are very small, less than 8 km in diameter, and there has been some controversy about whether these objects can be classed as moons or just space rocks. However all newly found satellites are still being offically named until a decision has been made about what characteristics determines true moon-ness.
Below are some of the newly discovered moons with naming schemes following tradition
