Before discussing how to classify planets, it's important to understand what a planet is. TheInternational Astronomical Unioncame out with an official definition in 2006, but that definition has remained controversial. The definition states thata planet is a celestial bodythat is in orbit around th...
You can also classify satellites based on their height above Earth's surface. Using this scheme, there are three categories [source:Riebeek]: Low-Earth orbits (LEO)— LEO satellites occupy a region of space from about 111 miles (180 kilometers) to 1,243 miles (2,000 kilometers) above Ea...
000 exoplanets (and many more coming!) need to be classified, often in the absence of enough physical data to do so. Whether preliminary designations such as ocean planets or super-Earths should be officially considered new classes
Some robots usestereo visionto see the world around them. Two cameras give these robots depth perception, and image-recognition software gives them the ability to locate and classify various objects. Robots might also usemicrophonesandsmellsensors to analyze the world around them. Boston Dynamics' ...
