The two bodies have a barycenter outside of both. By some provisional definitions, and certainly by some definitions in informal use, both are planets, and as such would be considered a binary planetary system." This is the view of the professional community. You didn't answer the question. Are those your words, yes or no? " This is similar to the Earth-Moon system. The Moon isn't in orbit around the Earth, and it is spherical. So it could be considered to have planet status. But as long as the Earth-Moon barycenter remains inside the Earth, the Moon is likely to remain categorized as a moon. In a few billion years, the barycenter will be above Earth's surface, and this system might be treated as a binary planet. Not that there's likely to be any intelligent species around to make that judgment." This is the view of the professional community. You didn't answer the question. Are those your words, yes or no? |
