Extrasolar planet
- HD 1237 differs from the sun in that HD 1237 is much younger, has high metallicity, has much cooler temperature and is in a binary system. As of 2000, it has been confirmed that an extrasolar planet orbits the star. It is of note for being a relatively Sun-like star not very far from the Sun that is home to an extrasolar planet.

An exomoon or extrasolar moon is a natural satellite that orbits an exoplanet or other non-stellar extrasolar body. [2] Exomoons are difficult to detect and confirm using current techniques, [3] and to date there have been no confirmed exomoon detections. [4]
May 3, 2024 · Most of the planets discovered outside our solar system don’t have orbits like Earth’s. Either the planets are closer to their stars, with orbital periods of only a few days, or they have highly elliptical orbits – some of which better resemble the paths of comets. Recently, however, a team of astronomers from the Geneva Observatory in ...
We analyse the magnetic activity characteristics of the planet hosting Sun-like star, HD 1237, using HARPS spectro-polarimetric time-series data. We find evidence of rotational modulation of the magnetic longitudinal field measurements consistent with our ZDI analysis, with a period of 7 days.
May 5, 2024 · Extrasolar planet, any planetary body that is outside the solar system and that usually orbits a star other than the Sun. Extrasolar planets were first discovered in 1992. More than 5,000 are known, and almost 9,000 await further confirmation.
We update orbits for 83 additionalexoplanets, including many whose orbits have not been revised sincetheir announcement, and include radial velocity time series from theLick, Keck, and Anglo-Australian Observatory planet searches.
