Key Features of KOI-7913 b

  • Distance from Earth: KOI-7913 b is situated at a considerable distance of 885 light-years from our planet. Despite this vast separation, advancements in space exploration technologies have allowed scientists to study its characteristics in detail.

  • Stellar Magnitude: With a stellar magnitude of 14.23, KOI-7913 b is not visible to the naked eye from Earth. This relatively faint brightness is typical for distant exoplanets, but it doesn’t deter astronomers from analyzing it through telescopes and space-based observatories.

  • Planet Type: KOI-7913 b is categorized as a Neptune-like planet. These planets share many characteristics with Neptune, such as their gaseous composition, thick atmospheres, and lower densities compared to rocky planets like Earth. Neptune-like planets are often larger than Earth and have a mix of hydrogen, helium, and other gases in their atmospheres.

Mass and Size

  • Mass: KOI-7913 b has a mass that is approximately 6.08 times that of Earth. This mass multiplier places it among the more massive exoplanets, which could indicate a substantial atmosphere, similar to that of Neptune.

  • Radius: With a radius roughly 0.209 times that of Jupiter, KOI-7913 b is smaller than many gas giants but still quite large compared to Earth. Its smaller radius in relation to Jupiter hints at a higher density, which could suggest interesting properties about its internal composition.

Orbital Characteristics

  • Orbital Radius: The orbital radius of KOI-7913 b is 0.1456 AU (Astronomical Units). This places the planet much closer to its host star than Earth is to the Sun, likely affecting its atmospheric conditions and surface temperatures.

  • Orbital Period: KOI-7913 b completes an orbit around its star in 0.0665 days, or about 1.6 hours. This incredibly short orbital period indicates that KOI-7913 b is a “hot planet,” likely experiencing extreme temperatures due to its proximity to its star.

  • Eccentricity: The orbital eccentricity of KOI-7913 b is 0.0, meaning it follows a perfectly circular orbit. This suggests stable and predictable orbital dynamics that might make it easier for astronomers to track and study the planet over time.

Detection Method

KOI-7913 b was detected using the Transit Method, which is one of the most common techniques for discovering exoplanets. This method involves observing the dimming of a star’s light as a planet passes in front of it, known as a transit. By measuring the amount of light blocked and the duration of the transit, scientists can infer important details about the planet’s size, orbit, and composition.

Conclusion

KOI-7913 b is a remarkable Neptune-like exoplanet that provides astronomers with an exciting opportunity to learn more about the variety of planets beyond our Solar System. With its unique size, mass, and orbital characteristics, it helps to expand our understanding of how planets form and evolve. As technology continues to improve, future observations may reveal even more about KOI-7913 b’s atmosphere and surface, offering potential clues about the conditions on planets outside our solar system.
