planet4629was

Planet4629was is a rocky exoplanet that orbits the sun-like star Lumen-4629, located roughly 180 light-years from Earth. The planet was identified in 2023 by the Asteria Exoplanet Survey as a periodic transit signal in the star’s light curve. After initial validation, the object circulated under the designation planet4629was in several catalogs and has been used as the informal name in scientific summaries.

Orbit and physical characteristics: The planet completes an orbit every 12.3 days and sits at a semi-major axis of about 0.112 AU with a low eccentricity around 0.04. Radius is measured at about 1.34 Earth radii, and mass around 2.1 Earth masses, implying a rocky density near 5.5 g/cm^3. The equilibrium temperature is estimated near 850 K, indicating a hot, close-in world.

Host star: Lumen-4629 is a G-type main-sequence star with a temperature of approximately 5700 K and nearly solar metallicity. It lies about 180 light-years away and has an estimated age of 4.5 to 5.5 billion years.

Observations and significance: Currently, no atmospheric signature has been detected in transit spectroscopy; the combination of high temperature and possible atmospheric loss makes a thick atmosphere unlikely. The planet is therefore categorized as a small, rocky super-Earth that is not within its star’s habitable zone. Ongoing radial-velocity campaigns aim to refine its mass and search for additional companions in the system, while planned transit spectroscopy attempts may attempt to detect any tenuous atmosphere.
