How can we tell given the new definition of planet? We can determine if it orbits a star and estimate its mass. How do we know it has cleared its orbit? It not a good day to be an astronomer.

Science has little to do with what is but everything to do with how we observe what is. If our definition precludes observing planets outside of the solar system - then best we can say is the objects orbiting other stars are possible planets or candidate planets - since one of the criteria is not observable. Where am I wrong?

um, it's always a good day to be an astronomer. And yes there are planets outside the solar system. the universe doesn't give a sh** how we define things.

I am guessing yes there are planets outside of the solar system. A way to tell there is a planet is because of the mass and the gravity would be aventually pulling the ship torward it.

it depends upon the definition of the solar system - what is its range?
also depends upon the definition of a planet.
there is no unique answer that does not depend upon opinion
definitions extablished by a majority can work temporarily - but the majority is sometimes wrong when time passes

Of course. Why wouldn't there be? The sun is a typical star.
