Sizing Up Exoplanets: This chart compares artists' concepts of the smallest known exoplanets, or planets orbiting outside the solar system, to our own planets Mars and Earth. Image credit: NASA/JPL-Caltech Click image for multiple resolutions and full caption. 'Honey I Shrunk the Planetary System': This artist's concept compares the KOI-961 planetary system to Jupiter and the largest four of its many moons. Image credit: NASA/JPL-Caltech Astronomers using data from NASA's Kepler mission have discovered the three smallest planets yet detected orbiting a star beyond our sun. The planets orbit a single star, called KOI-961, and are 0. 78, 0. 73 and 0. 57 times the radius of Earth. The smallest is about the size of Mars. All three planets are thought to be rocky like Earth, but orbit close to their star.

"It's actually more similar to Jupiter and its moons in scale than any other planetary system. The discovery is further proof of the diversity of planetary systems in our galaxy."

Key:

• Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
• The Mean is meant to be an indicator of an individual's average comment sentiment.
• The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).

Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
