| | ESPs: California Scientist Discovers First Extrasolar Planet Under Three Suns - Planetary News The Planetary Society |
 | | The main star of HD 188753, which is similar to our own Sun, would be yellow and appear as a very large object in the sky since the planet's "year" is only three-and-a-half days long, Konacki pointed out. |
 | | In the case of HD 188753, the two stellar companions would truncate the disk around the main star to a radius of only 1.3 AU, leaving, essentially, no space for a planet to form. |
 | | Hence, I suspect that HD 188753's planet probably formed via a rapid formation process, before the multiple system evolved to its present state, and that seems to imply disk instability was at work. |
