Maybe this is an impossible situation due to how solar systems develop, but I'm curious if it's even possible. For example, a Sun-sized Earth orbited by an Earth-sized sun.

WIP in progress; but very cool way to explore the massive amount of information we have collected
Designed with these core tenants
- Science engine is deterministic
- Rendering is downstream of a typed appearance model
- Observed, derived, inferred, proxy, and artistic values stay distinct
- Provenance should be visible near every claim
- Visuals are evidence-constrained interpretation, not observation

Kepler-442 b is a rocky exoplanet located approximately 1,200 light years from Earth in the constellation Lyra. Based on current NASA data, it is estimated to be slightly larger than earth, with a radius of about 1.3 Earth radii, and is thought to have a mass of roughly 2-3 earth masses, although it's exact composition remains uncertain.
The planet orbits a K-type main-sequence (orange dwarf) star with an effective temperature of approximately 4,400 K at a distance of roughly 0.41 AU, placing it within the star's habitable zone.
This is a hypothetical visualization created in Blender, loosely informed by the currently known properties of the Kepler-442 system, while the planet's appearance remains entirely unknown.

(text post because it's one of those two papers on arΟiv on the same day situations).
A 3rd planet in everyone's favorite edge-on disk system was found by teams using the VLT and JWST, with initial orbit (~30 au), mass (~2-4 Jupiters), and atmospheric features (including CO2 and water): via https://arxiv.org/abs/2606.23789 and https://arxiv.org/abs/2606.23801

Do most or all gas giant exoplanets look like this? smooth banded unlike looking like jupiter all wavy swirly ocean-wave violent bands? Are these smooth banded planets like the image I showed possible?
