Habitable exoplanet visualizer

Not sure if this is of interest, but I built this so I could get some understanding of exoplanet data for a sci-fi novel I'm writing.

Note, I defined "habitable zone" as sqrt(10^st_lum) between .9 and 1.67. Most are not likely habitable planets,

Looking for climate models in planets orbiting Binaries

I am looking for help to find climate models for exoplanets orbiting binaries or more suns. It could be at distant binaries, but more specifically for planets orbiting small red dwarfs that orbit sun-like or greater suns. Have you ever heard about such a study?

Dyson Sphere

Hey everyone! I’m 15 and super passionate about space and futuristic tech. Recently, I’ve been daydreaming about something crazy—a Dyson Sphere to capture energy from the Sun. I know it sounds wild, but I think it could change everything. I’m just starting out, and I’m looking to learn about satellite tech, space engineering, and how big projects like this might actually work. If anyone has advice, cool resources, or just wants to chat about this kind of stuff, I’d love to connect! And maybe it's possible to build one in 6-10 years in the future...if you are interested, you can reach out to me.

About detecting Earth-like planets in the inhabitable zone of its star.

I know some planets are far easier to detect than others. Considering our state of the art technology, how good are we at detecting a potential Earth-sized rocky planet orbiting within the inhabitable zone of its solar system (basically would we be able to detect an actual "twin planet" orbiting around a really distant star).

If it is currently very difficult, when, do you think, would we become good at it ?

My own made categories on cosmic bodies that are different types

Explaining my own made categories
Exoplanets are planets that do not come from solar system
Exomoons are moons that did not come from solar system, like, exomoons orbiting exoplanets. Jupexoplanets are planets that are the similar size or bigger than jupiter Uranexoplanets are planets that spin on their side.
Saturexoplanets are planets which have rings Neptexoplanets are planets that are very cold planets like neptune.
Exoasteroids are asteroids that do not come from solar system. same with exocomets and exorocks that do not come from solar system.

What do you all think?
