Borrelly
Alphonse Louis Nicolas Borrelly (December 8, 1842 – February 28, 1926) was a French astronomer. He joined the Marseille Observatory in 1864. In the course of his career, he discovered a number of asteroids and comets, including the periodic comet 19P/Borrelly. The French Academy of Sciences awarded him the Valz Prize, Prix Valz for 1903 and the Lalande Prize, Prix Lalande for 1909. The asteroid 1539 Borrelly was named in his honor. In 1913, he received the Prix Jules Janssen, the highest award of the Société astronomique de France, the French astronomical society.

19P/Borrelly
Comet Borrelly or Borrelly's Comet (official designation: 19P/Borrelly) is a periodic comet, which was visited by the spacecraft Deep Space 1 in 2001. The comet last came to perihelion (closest approach to the Sun) on February 1, 2022 and will next come to perihelion on December 11, 2028. Deep Space 1 returned images of the comet's nucleus from 3400 kilometers away. At 45 meters per pixel, it was the highest resolution view ever seen of a comet. Discovery The comet was discovered by Alphonse Borrelly during a routine search for comets at Marseilles, France on December 28, 1904. Deep Space 1 flyby On September 21, 2001 the spacecraft Deep Space 1, which was launched to test new equipment in space, performed a flyby of Borrelly. It was steered toward the comet during the extended mission of the craft, and presented an unexpected bonus for the mission scientists. Despite the failure of a system that helped determine its orientation, Deep Space 1 managed to send back to Ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comet
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several mill ...

246 Asporina
Asporina (minor planet designation: 246 Asporina) is a sizeable main-belt asteroid. It is classified as one of the few A-type asteroids. It was discovered by A.

308 Polyxo
Polyxo ( minor planet designation: 308 Polyxo) is a main-belt asteroid that was discovered by A. Borrelly on March 31, 1891, in Marseilles. It is orbiting the Sun at a distance of with a low orbital eccentricity (ovalness) of 0.04 and a period of . The orbital plane is tilted at an angle of 4.36° to the plane of the ecliptic. 308 Polyxo is classified as a rare T-type asteroid, with a spectrum that bears some similarity to the Tagish Lake meteorite. A spectral feature at a wavelength of suggests aqueous alteration of some surface materials. Photometric measurements reported in 1983 give a rotation period of 12.03 hours and a brightness variation of 0.20 in magnitude. The adaptive optics instrument at the W. M. Keck Observatory shows an oblate object with a diameter of 130 km. The size ratio between the major and minor axes is 1.26 ± 0.11. Light curves for this object suggests it has a very irregular shape.

268 Adorea
268 Adorea is a very large main belt asteroid, about in width. It was discovered by A. Borrelly on 8 June 1887 in Marseilles. This asteroid is a member of the Themis family and is classified as a primitive carbonaceous F-type/C-type asteroid. It is orbiting the Sun at a distance of with an orbital eccentricity (ovalness) of 0.14 and a period of . The orbital plane is tilted at an angle of 2.44° to the plane of the ecliptic. From February 23 until March 2, 2006, photometric measurements were taken of the asteroid. These were used to produce a light curve showing a rotation period of with a brightness variation of in magnitude. This result is consistent with some, but not all previous results. Some studies had suggested a longer rotation period of ; double the time measured. However, the new data is inconsistent with the longer period. In May 1979, 268 Adorea was positioned in proximity of the galaxy NGC 4517 and as a bright new light source it was identified as a potentia ...

198 Ampella
Ampella (minor planet designation: 198 Ampella) is a Main belt asteroid that was discovered by Alphonse Borrelly on June 13, 1879. The name seems to be the feminine form of Ampelos, a satyr and good friend of Dionysus in Greek mythology. It could also derive from the Ampelose (plural of Ampelos), a variety of hamadryad. It is an S-type asteroid. So far Ampella has been observed occulting a star once, on November 8, 1991, from New South Wales, Australia. This asteroid has been resolved by the W. M. Keck Observatory, resulting in a size estimate of 53 km. It is oblate in shape, with a size ratio of 1.22 between the major and minor axes. Measurements from the IRAS observatory gave a similar size estimate of 57 km. Photometric measurements made in 1993 give a rotation period The rotation period of a celestial object (e.g., star, gas giant, planet, moon, asteroid) may refer to its sidereal rotation period, i.e. the time that the object takes to complete a single revolutio ...
