The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Its orbit revealed that it was a new planet, Uranus, the first ever discovered telescopically. [20] Giuseppe Piazzi discovered Ceres in 1801, a small world between Mars and Jupiter. It was considered another planet, but after subsequent discoveries of other small worlds in the same region, it and the others were eventually reclassified as ...
[1] [2] Sputnik 2: 3 November 1957 Earth orbiter, first animal in orbit, a dog named Laika [2] [3] [4] Explorer 1: 1 February 1958 Earth orbiter; discovered Van Allen radiation belts [5] Vanguard 1: 17 March 1958 Earth orbiter; oldest spacecraft still in Earth orbit [6] Luna 1: 2 January 1959
The 2006 IAU redefinition of planet excludes the possibility of double planets. [24] [25] [26] 15760 Albion: 1992 unknown Trans-Neptunian object: When discovered, these bodies were briefly hailed as the tenth and eleventh planets by the press, but it was then decided that 15760 Albion was the prototype of trans-Neptunian objects or cubewanos ...
If the Sun–Neptune distance is scaled to 100 metres (330 ft), then the Sun would be about 3 cm (1.2 in) in diameter (roughly two-thirds the diameter of a golf ball), the giant planets would be all smaller than about 3 mm (0.12 in), and Earth's diameter along with that of the other terrestrial planets would be smaller than a flea (0.3 mm or 0. ...
A Belgian-led team made the discovery using both space- and ground-based telescopes, spotting the planets as they passed in front of the red dwarf star known as TRAPPIST-1.
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 newly-found ETNO joins Sedna, a dwarf planet believed to be about 250 AU from the sun, as objects residing outside the Kuiper Belt, where Pluto resides, according to Space.
