I think I see what you are saying. First of all, the plane of the solar system is relative. You can make a plane with the sun and neptune's orbit and get a completely different plane from the sun and earth's orbit.

But to answer your question, no. The distance to even the nearest star at over 4 light years away is too distant, and thus gravity too weak, to cause any kind of orbiting phenomena with our neighbors. Us and all of our neighbors are already in orbit around the center of the Milky Way, as you pointed out.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
