Antonín Mrkos
Antonín Mrkos () (27 January 1918, Střemchoví – 29 May 1996, Prague) was a Czechs, Czech astronomer. Biography Mrkos entered the University in Brno in 1938. His studies were interrupted by the onset of World War II, and in 1945 he became a staff member at the Skalnaté Pleso Observatory in Slovakia. It was from here that he carried out his extremely active cometary programme and became the discoverer of several unusual comets, the most famous of them the bright Comet 1957d. He was the second Czech in Antarctica and the first Czechoslovak to reach the Southern Pole of Inaccessibility as a member of the 3rd Soviet Antarctic Expedition (1957–1959). The Czechoslovakian flag was the second flag raised after the flag of the USSR. He returned to Antarctica as the head of the four-member Czechoslovakian crew in the seventh List of Antarctic expeditions by the Soviet Union, Soviet Antarctic Expedition (1961–1963). He was studying aurora (astronomy), auroras among other thin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C/1947 Y1
This is a list of parabolic and hyperbolic comets in the Solar System. Many of these comets may come from the Oort cloud, or perhaps even have interstellar origin. The Oort Cloud is not gravitationally attracted enough to the Sun to form into a fairly thin disk, like the inner Solar System. Thus, comets originating from the Oort Cloud can come from roughly any orientation (inclination to the ecliptic), and many even have a retrograde orbit. By definition, a hyperbolic orbit means that the comet will only travel through the Solar System once, with the Sun acting as a gravitational slingshot, sending the comet hurtling out of the Solar System entirely unless its eccentricity is otherwise changed. Comets orbiting in this way still originate from the Solar System, however. Typically comets in the Oort Cloud are thought to have roughly circular orbits around the Sun, but their orbital velocity is so slow that they may easily be perturbed by passing stars and the galactic tide.

C/1957 P1
Comet Mrkos, formally known as C/1957 P1 (old style ''1957d''), was a non-periodic comet discovered in 1957 by Antonín Mrkos. It was one of two bright comets that had their perihelion in 1957, the other being Comet Arend–Roland. Its peak magnitude was estimated to be around 1 and it has been characterised as a great comet. Observations The comet was discovered by Czech astronomer Antonin Mrkos by naked eye at the observatory on Lomnický štít, Czechoslovakia. He announced its discovery on August 2, 1957, but by that point it had already been discovered independently by others, with a report of observation from Japan dated July 29. However, the comet became known as comet Mrkos, as Mrkos' telegram was the first to arrive at the IAU. The comet was then near perihelion and its apparent magnitude was estimated to be around 2. By August 4 it had brightened to magnitude 1. At the time of discovery the comet was near perihelion and located near Pollux in the constellation Gemini. ...

124P/Mrkos
This is a list of periodic comets that were numbered by the Minor Planet Center after having been observed on at least two occasions. Their orbital periods vary from 3.2 to 366 years. there are 436 numbered comets (1P–436P), most of them being members of the Jupiter-family (JFC). There are also 31 Encke-type comets (ETCs), 14 Halley-type comets (HTCs), five Chiron-type comets (CTCs), and one long-period comet ( 153P). About a third of these bodies are also near-Earth comets (NECs). In addition, eight numbered comets are principally classified as minor planets – five main-belt comets, two centaurs (CEN), and one Apollo asteroid – and display characteristics of both an asteroid and a comet. Occasionally, comets will break up into multiple chunks, as volatiles coming off the comet and rotational forces may cause it to break into two or more pieces. An extreme example of this is 73P/Schwassmann–Wachmann, which broke into over 50 pieces during its 1995 perihelion. For a lar ...

Comet Mrkos-Honda
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 mil ...
