Hubble’s mirror is 2.4 m, while Webb’s is 6.5 m. So - yes! @NASANewHorizons images of Pluto still rule, but Webb will complement them with amazing spectroscopy to study surface composition. More:https://asd.gsfc.nasa.gov/blueshift/index.php/2015/07/08/pluto/ …
Earth is too bright for #Webb to observe, but looking at other objects in our solar system (as well as other planets in other solar systems) will help us gain insights about our own home. https://go.nasa.gov/2QZTWqW #NASA60th #JWSTpic.twitter.com/bUs5Mb98aT

Webb’s sensitive infrared cameras are cooled to just 7 degrees above absolute zero. The Earth’s warmth would swamp them.

We can learn a lot about Earth by studying the solar system at large, and by studying planetary systems around other stars.
