    en.wikipedia.org/wiki/File:Video-FlyOver-Dwarf...

    A new video animation of dwarf planet Ceres, based on images taken by NASA's Dawn spacecraft, provides dramatic flyover views of this heavily cratered, mysterious world. The images come from Dawn's first mapping orbit at Ceres, at an altitude of 8,400 mile (13,600 kilometers), as well as navigational images taken from 3,200 miles (5,100 ...

  3. Habitability of yellow dwarf systems - Wikipedia

    en.wikipedia.org/wiki/Habitability_of_yellow...

    A G2V-type yellow dwarf like the Sun belongs to Kepler-452, with an estimated age of 6 billion years (6 Ga) versus the solar system's 4.5 Ga. [ 46 ] The mass of its star is slightly higher than that of the Sun, 1.04 M ☉ , so despite the fact that it completes an orbit around it every 385 days versus 365 terrestrial days, it is warmer than the ...

  4. G-type main-sequence star - Wikipedia

    en.wikipedia.org/wiki/G-type_main-sequence_star

    A G-type main-sequence star (spectral type: G-V), also often, and imprecisely, called a yellow dwarf, or G star, is a main-sequence star (luminosity class V) of spectral type G. Such a star has about 0.9 to 1.1 solar masses and an effective temperature between about 5,300 and 6,000 K (5,000 and 5,700 °C ; 9,100 and 10,000 °F ).

    The team studied Leo P using NASA’s James Webb Space Telescope, which imaged the dwarf galaxy with the instrument's Near-Infrared Camera, or NIRCam. By observing the galaxy in infrared light ...

  6. 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.

  7. List of possible dwarf planets - Wikipedia

    en.wikipedia.org/wiki/List_of_possible_dwarf_planets

    The number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt [1] and over 10,000 in the region beyond. [2] However, consideration of the surprisingly low densities of many large trans-Neptunian objects, as well as spectroscopic analysis of their surfaces, suggests that the number of dwarf planets may be much lower, perhaps only nine among ...

  8. List of exoplanets discovered by the Kepler space telescope

    en.wikipedia.org/wiki/List_of_exoplanets...

    An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.

    The naked eye planets, which include Mercury, Mars, Jupiter, and Saturn, will not all become visible in Tennessee until around 5 a.m. Central Time, since Mercury and Jupiter are very low in the sky.
