Opening and title
Wikipedia was first discovered on September 8, 1997 at the CERGA Observatory as part of the OCA-DLR project [5] . Upon registration, the property was designated 1997 RO 4 . But the data obtained was not enough to calculate the orbit.
In March - April 2007, the asteroid was registered by Mount Lemmon and the Spacewatch project [5] . However, he received the designation 2007 FK 34 .
Finally, on August 25, 2008, the asteroid was discovered at the Andrushev Astronomical Observatory [5] . When registering the discovery, the object was assigned the designation 2008 QH 24 [6] .
On April 18, 2011, the object was included in the catalog of minor planets under number 274301 [7] .
The proposal to name one of the Wikipedia asteroids discovered in Zhytomyr came from Wikipedia and member of the board of the public association Wikimedia Ukraine Andrei Makuhi [8] . With the initiative to name the celestial body in honor of the free encyclopedia , the founder of the Andrushev Observatory Yuri Ivaschenko addressed the Committee on the Nomenclature of Minor Planets . The proposal was approved by all members of the committee, and on January 27, 2013 the asteroid officially received a new name [1] [3] .
The note added to the Circular of Small Planets [2] No. 82403 reads [9] :
Wikipedia is a free, co-editable online encyclopedia launched in 2001. After 11 years from the beginning of its compilation, it has become one of the largest reference works and one of the most visited websites on the Internet. It is written by enthusiasts from around the world in more than 270 languages.
Original textWikipedia is a free, copyleft, collaboratively edited online encyclopedia launched in 2001. In 11 years of its compilation it became one of the largest reference works and one of the most visited web-sites on the Internet. It is developed in more than 270 languages by enthusiasts from all over the world.
According to several media reports, such a decision, dedicated to the “birthday” of Ukrainian Wikipedia [10] , makes the asteroid “the first monument to Wikipedia and Wikipedia around the world” [1] [4] .
Orbital characteristics
Wikipedia circulates in the middle of the Main Asteroid Belt at an average distance of 2.382 a. e. (356.3 million km) from the Sun. Its orbit has a small eccentricity of 0.1455 and an inclination of 6.732 °. Thus, the maximum distance from Wikipedia to the Sun is 2.728 a. e. (408.2 million km), the minimum - 2.035 a. e. (304.5 million km).
The Wikipedia period of revolution around the Sun is 3.68 years (1343 days).
The absolute magnitude of Wikipedia is 16.9 m . Its visible luster during the synodic period varies between 18.8-22.5 m [11] .
Physical Characteristics
The size of Wikipedia has not been established, but, based on its brightness, it can be, depending on the albedo , from 1 to 2 km [12] .
Presumably composed of stone and metal [1] [2] . Outwardly, it is practically indistinguishable from similar celestial bodies from the main asteroid belt [1] [4] .
