They include ethane (C 2 H 6), acetylene (C 2 H 2), methylacetylene (CH 3 C 2 H), and diacetylene (C 2 HC 2 H). [ 102 ] [ 105 ] [ 106 ] Spectroscopy has also uncovered traces of water vapour, carbon monoxide , and carbon dioxide in the upper atmosphere, which can only originate from an external source such as infalling dust and comets .
The Sun is the star at the center of the Solar System.It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.
Ceres (minor-planet designation: 1 Ceres) is a dwarf planet in the middle main asteroid belt between the orbits of Mars and Jupiter.It was the first known asteroid, discovered on 1 January 1801 by Giuseppe Piazzi at Palermo Astronomical Observatory in Sicily, and announced as a new planet.
