Description
A real solar system at a distance of 12.5 light years in the constellation Aries. At least 2 "earth-like" planets orbit a faint, small red dwarf named „Teegarden’s Star”. The system is with about 8 billion years much older than our solar system.
The planet „Teegarden b” moves in the habitable zone and receives slightly more (115%) radiation from its faint parent star, mainly infrared light. Due to the lack of visible light, the surface of the planet is bathed in a dim yellow-reddish twilight, similar to just after sunset on Earth. However, the bright disk of the parent star is considerably larger as seen from the planet than the sun is from Earth (4.5x). You can look into it, but it quickly becomes uncomfortable. If planet b has an atmosphere, water and/or ice could also be present. The planet is most likely in bound rotation, that means it always show the same side to its parent star, like the moon to the earth. The sun is always at the same place in the sky. There is no "day" and no "night", only a day side and a night side.This is not favorable for the development of life, but it is not impossible.
The small whitish dot near the sun is „Teegarden c”, the second, outer planet in the system.
