The number of exoplanets (planets outside the solar system orbiting other stars) discovered last year have totalled twenty eight. They are among 37 of the new objects identified in 2006, seven of which are brown dwarf stars, or stars that failed to ignite. Jason Wright of the University of California says "We added 12 percent to the total in the last year, and we're very proud of that." The increasing number of exoplanets have shown that many types exist. Shown is a comparison of planets of the Upsilon Andromedae system and planets of the inner solar system of the Sun.
