    1. A definition like that will let a lot more of the solar system’s bits of rocky debris count as planets.

      Well, that will cause confusion!

    2. I learn from space.com that a research group is going to try to get a new geophysical definition of the word planet approved by the International Astronomical Union, and is drafting it in a way that will allow Pluto to count as a planet once more. (It lost that status in 2006 and was reclassified as a dwarf planet.)

      Fingers crossed!

    1. The planets orbit a dwarf star named Trappist-1, about 40 light years, or about 235 trillion miles, from Earth. That is quite close, and by happy accident, the orientation of the orbits of the seven planets allows them to be studied in great detail.

      This is amazing news! So exciting!
