Planets of Our Solar System

Our solar system officially has eight planets and one star: the Sun. The discovery of an object larger than Pluto in 2005 rekindled the debate over whether such objects, belonging to the Kuiper Belt – a collection of icy bodies located beyond Neptune – should be called planets. Pluto and other large members of the Kuiper Belt are now considered “dwarf planets.”

substitute: Surface of Mars, photographed by Mars Express, 31st May 2007.

84°S 280°E to 75°S 266°E; the top (southernmost) of the image shows the terminus of the Australe Scopuli, fading into Parva Planum.

The vivid violet areas at the bottom of the 3rd and 4th images are where the red channel was blown out; I used the infrared image for this, rather than the (visible) red light image because the latter was even more glitched.
