What is KOI-5715.01?

KOI-5715.01 is an exoplanet measured to be approximately 3000 light years away from the Earth. This exoplanet is considered to be the best candidate for a super habitable world as of March 2023. It is a massive rocky planet nearly 93% larger than the size of the Earth orbiting within the Goldilocks Zone of its host star (habitable orbiting zone). This means that the conditions are perfect for liquid water to exist on the exoplanet's surface, a necessity for life on Earth to thrive and survive.

The oceans and terrains are massive, giving us a luxurious amount of space to settle into. There would be so much more land for life to thrive on compared to Earth.

The equilibrium temperature on exoplanet KOI-5715.01 is 260 K = 8.33 F° = -13.15 C° (found here)

There isn't much known about this exoplanet and CalTech is still in the process of researching and verifying our current knowledge about the suitable exoplanet.

Gravitational Acceleration

The gravitational acceleration on planet Earth is approximately ~9.81 m/s^2 as commonly known to all. But let's calculate the gravitational acceleration on the surface of planet KOI-5715.01:

Variables:
This information can be found here. I am also assuming exoplanet KOI-5715.01 is composed of mostly the same substances as Earth and the proper proportions of each (technically very low chance).
- Radius of KOI-5715.01 = 1.23098e+7 m
- Mass of KOI-5715.01 = Earth Mass * 1.93 = 5.97219e+24 kg * 1.93 = 1.15263e+25 kg (found here)
- G = 6.67430e-11
Formulas:
- F = G * m1 * m2 / r^2
- F = m * a
Calculation:
a = (G * m1 * m2 / r^2) / (m2) = G * m1 / r^2
a = 6.67430e-11 * 1.15263e+25 / (1.23098e+7)^2 = 5.07684 m/s^2

Conclusion: In short, the gravity would be a little less stronger than here on Earth, and it would be a little more stronger than on Mars. With the gravity being only ~5.08 m/s^2, humans might be able to hover and have higher jump times and feel less pressure on them. These conditions are satisfactory for life to exist on the exoplanet already and can sustain human life on it as well.

Why is KOI-5715.01 so special?

The exoplanet KOI-5715.01 orbits a very rare and special type of star. It is an orange dwarf star that is smaller than our Sun (yellow dwarf star). Orange dwarf stars typically last upto 70 billion years compared to our Sun which is only 10 billion years and halfway through its lifespan. Life on a planet that was given the chance 70 billion years to evolve must be very advanced and amazing. In nearly 5 billion years, the Sun will grow so large that it engulfs the Earth and all life on it.
