Kepler 1229 b Planet

Embark on a cosmic odyssey as we unravel the intricacies of Kepler-1229 b, a super Earth exoplanet dancing in orbit around a red dwarf star. From its discovery to physical characteristics and the quest for habitability, join us in a detailed exploration of this alien world.

Kepler 1229 b Size Compared to Earth in Percentage

The size of Kepler 1229 b is given as 1.40 R🜨 (radius). To express this in percentage compared to Earth, we use the formula: (Radius of Kepler 1229 b/Radius of Earth)×100. Plugging in the values, we get (1.40/1.49)×100=94.00%. Therefore, Kepler 1229 b is approximately 94.00% of Earth's size.

Kepler 1229 b Mass Compared to Earth in Percentage

The mass of Kepler 1229 b is provided as 2.7 Earths. To express this in percentage compared to Earth, we use the formula: (Mass of Kepler 1229 b/Mass of Earth)×100. Plugging in the values, we get (2.7/1)×100=270%. Therefore, Kepler 1229 b has a mass approximately 270% of Earth's mass.

Physical Characteristics

Size and Composition

Kepler-1229 b, a confirmed super-Earth, mirrors Earth in size but orbits a red dwarf, Kepler-1229. With a mass of 2.7 times that of Earth, it leans toward a rocky composition, distinguishing it from gas giants like Neptune and Uranus.

Starry Companion

The red dwarf star, Kepler-1229, plays a central role in the exoplanet's narrative. With only 0.54 times the mass and 0.51 times the radius of the Sun, Kepler-1229 boasts a temperature of 3724 K and an age of 3.72 billion years. Its faint apparent magnitude of 15.474 places it beyond the reach of the naked eye.

Orbital Ballet

Kepler-1229 b twirls around its host star with 4% of the Sun's luminosity, completing an orbit every 86.829 days at a close distance of 0.2896 AU—reminiscent of Mercury's proximity to our own sun.

Habitable Zone Dance

Situated in the habitable zone, Kepler-1229 b sparks curiosity about its potential to host liquid water. With a radius of 1.4 R🜨, it leans towards rockiness, offering a tantalizing prospect for habitability.

Tidally Locked Tension

The likelihood of Kepler-1229 b being tidally locked raises questions about extreme temperature differentials. Yet, within the terminator line, a narrow zone between scorching heat and eternal darkness, temperatures of around 273 K (0 °C; 32 °F) could foster liquid water. The presence of a robust atmosphere might further extend habitable regions.

Red Dwarf Longevity

Kepler-1229's status as a red dwarf positions it as a stellar longevity champion, with the potential to outshine the Sun by living up to 50–60 billion years. This longevity could significantly impact the exoplanet's chances of sustaining life.


Kepler-1229 b emerges not merely as a distant exoplanet but as a captivating enigma in the cosmos. As we peer into the complexities of its red dwarf orbit, size, and potential habitability, the mysteries of this alien world invite us to contemplate the vast possibilities that lie beyond our celestial neighborhood. The journey continues, with future telescopes poised to unveil more secrets, expanding our understanding of the cosmic tapestry that Kepler-1229 b is part of.
