  2. Magnetosphere - Wikipedia

    en.wikipedia.org/wiki/Magnetosphere

    The magnetosphere of Jupiter is the largest planetary magnetosphere in the Solar System, extending up to 7,000,000 kilometers (4,300,000 mi) on the dayside and almost to the orbit of Saturn on the nightside. [17] Jupiter's magnetosphere is stronger than Earth's by an order of magnitude, and its magnetic moment is approximately 18,000 times ...

  3. Magnetosphere of Saturn - Wikipedia

    en.wikipedia.org/wiki/Magnetosphere_of_Saturn

    The magnetosphere of Saturn is the cavity created in the flow of the solar wind by the planet's internally generated magnetic field. Discovered in 1979 by the Pioneer 11 spacecraft, Saturn's magnetosphere is the second largest of any planet in the Solar System after Jupiter .

    en.wikipedia.org/.../Selected_images/15

    The magnetosphere of Jupiter is the cavity created in the solar wind by the planet's magnetic field.Extending up to seven million kilometers in the Sun's direction and almost to the orbit of Saturn in the opposite direction, Jupiter's magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the ...

  5. List of directly imaged exoplanets - Wikipedia

    en.wikipedia.org/wiki/List_of_directly_imaged_e...

    Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations. This method works best for young planets that emit infrared light and are far from the glare of the star.

  6. Solar System - Wikipedia

    en.wikipedia.org/wiki/Solar_System

    The orbits of Solar System planets are nearly circular. Compared to many other systems, they have smaller orbital eccentricity. [70] Although there are attempts to explain it partly with a bias in the radial-velocity detection method and partly with long interactions of a quite high number of planets, the exact causes remain undetermined. [70] [74]

  7. Planet - Wikipedia

    en.wikipedia.org/wiki/Planet

    The magnetosphere can be much larger than the planet itself. In contrast, non-magnetized planets have only small magnetospheres induced by interaction of the ionosphere with the solar wind, which cannot effectively protect the planet. [137] Of the eight planets in the Solar System, only Venus and Mars lack such a magnetic field. [137]

  8. List of multiplanetary systems - Wikipedia

    en.wikipedia.org/wiki/List_of_multiplanetary_systems

    The stars with the most confirmed planets are the Sun (the Solar System's star) and Kepler-90, with 8 confirmed planets each, followed by TRAPPIST-1 with 7 planets. The 1,033 multiplanetary systems are listed below according to the star's distance from Earth. Proxima Centauri, the closest star to the Solar System, has three planets (b, c and d).

  9. Stellar magnetic field - Wikipedia

    en.wikipedia.org/wiki/Stellar_magnetic_field

    The magnetosphere contains charged particles that are trapped from the stellar wind, which then move along these field lines. As the star rotates, the magnetosphere rotates with it, dragging along the charged particles. [13] As stars emit matter with a stellar wind from the photosphere, the magnetosphere creates a torque on the ejected matter.
