Comet Tucker, formally designated as C/2004 Q1, is a faint non-periodic comet that had a very distant perihelion on 11 December 2004. It was the second of two comets discovered by famed amateur astronomer, Roy A. Tucker .
The comet reached minimum elongation on 13 March, on 25°. [4] It reached its peak brightness in April. Jacobson spotted the comet with naked eye on April 18. David H. Levy reported that the comet had an apparent magnitude of 4.7 with the naked eye on April 24. In the end of April the tail of the comet was reported to be up to 2–3 degrees long.
The comet rapidly brightened as it slowly approached the Earth, and was closest at 0.757 AU (113.2 million km) on 2 August 1907. [4] Edward E. Barnard made a series of photographic observations of the comet between 11 July and 8 September 1907, where he described the comet being visible to the naked eye for two months. [ 5 ]
C/1961 O1 (Wilson–Hubbard) is a non-periodic comet discovered on 23 July 1961. The comet passed perihelion on 17 July, became visible in twilight on 23 July, having a long tail, and faded rapidly, becoming no longer visible with the naked eye after the first days of August.
Our solar system is full of floating space debris: Comets, meteors, asteroids and more. What are the differences that make up these various space rocks?
The word comet derives from the Old English cometa from the Latin comēta or comētēs. That, in turn, is a romanization of the Greek κομήτης 'wearing long hair', and the Oxford English Dictionary notes that the term (ἀστὴρ) κομήτης already meant 'long-haired star, comet' in Greek.
Comet LINEAR, formal designation C/2012 X1, is a non-periodic comet that was observed telescopically from 2012 to 2015. It produced a powerful outburst on 21 October 2013, which raised its brightness 100 times its expected magnitude from 12 to 8.5 for several months.
This unique spiral galaxy, which is situated 3.2 billion light-years from the Earth, has an extended stream of bright blue knots and diffuse wisps of young stars. [2] It rushes at 3.6 million km/h (1000km/s [2]) through the cluster Abell 2667 and therefore, like a comet, shows a tail, with a length of 600,000 light-years.
