2024年10月25日 · Wolf 503 b is a super Earth exoplanet that orbits a K-type star. Its mass is 6.27 Earths, it takes 6 days to complete one orbit of its star, and is 0.05712 AU from its star. Its discovery was announced in 2018.

2018年6月9日 · With its measured radius near the gap in the planet radius and occurrence rate distribution, Wolf 503b offers a key opportunity to better understand the origin of this radius gap as well as the nature of the intriguing populations of "super-Earths" and "sub-Neptunes" as a whole.

2018年9月6日 · Wolf 503b, an exoplanet twice the size of Earth, has been discovered by an international team using data from NASA ’s Kepler Space Telescope. The find is described in a new study led by Merrin Peterson, who just started her master’s degree at the Institute for Research on Exoplanets (iREx), at Université de Montréal (UdeM).

2018年9月6日 · Planet: Wolf 503b. Discovered by: Merrin Peterson, et al. Date: June 2018. Key Facts: A newly discovered planet twice as big around as Earth is about 145 light years away -- close enough to offer a prime target for follow-up investigations. The planet orbits a type of star known as an "orange dwarf," and is so close to the star that it ...

2018年6月20日 · The newly-discovered exoplanet, named Wolf 503b, has a radius two times that of Earth and represents one of the best opportunities to date to conduct a detailed study of a planet in the 1-4 Earth radii range.

2018年9月8日 · 科学家发现在距离我们的地球仅145光年远的地方有一颗地球大小两倍的系外行星，被命名为狼503b（Wolf 503b）。 图源：NASA Goddard/Robert Simmon (Earth), NASA / JPL (Neptune)) 研究人员指出，狼503b之所以有趣，不仅因为它的大小（它可能是一个“超级地球”），还因为它的运行轨道（它每六天绕其恒星旋转一次）。 系外行星就是我们太阳系之外的行星。 蒙特雷大学教授Bj?rn Benneke在一份声明中说：“狼503b是唯一一个半径正好的行星，这 …

2021年11月11日 · Wolf 503 b was found to be a 2.043 R ⊕ planet that completes one orbit roughly every 6 days. At 0.06 au from its star, Wolf 503 b has an equilibrium temperature of ∼800 K, an intermediate temperature compared to other sub-Neptunes discovered.

2021年7月16日 · Abstract: Using radial velocity measurements from four instruments, we report the mass and density of a $2.043\pm0.069 ~\rm{R}_{\oplus}$ sub-Neptune orbiting the quiet K-dwarf Wolf 503 (HIP 67285). In addition, we present improved orbital and transit parameters by analyzing previously unused short-cadence $K2$ campaign 17 photometry and conduct ...

2018年10月8日 · Wolf 503b is truly distinguished, as its size places it directly at the edge of the radius gap near 1.5–2.0 R ⊕, while its bright host star (H = 7.77 mag, V = 10.28 mag) makes it one of the best targets for radial velocity follow-up and transit spectroscopy at its size (Figure 8).

Wolf 503 b is an exoplanet orbiting the star Wolf 503, located about 145.4 light-years (44.6 pc) away from Solar System. Its discovery was publicly announced on 2018. The host star Wolf 503 has apparent magnitude of 10.3, with absolute magnitude of 7.0.
