A previously unknown
minor planet with a four-year rotation period around the Sun was discovered by
Uzbek astronomers in 2007 and officially included in the International Minor
Planet Catalog under the number 210271. The planet has been given the name
Samarqand.
“That was the first planet of this kind discovered in Uzbekistan”,
Shuhrat Egamberdiyev, director of
Mirzo Ulughbek Astronomy Institute, said in an interview. “The revelation
served as a convincing testimony to the considerable progress made by our
astronomers throughout independence years. At the request of scientists, President
of Uzbekistan Islam Karimov called the planet after one of the world’s greatest
cities – Samarqand. The title was approved by the Minor Planets Center of
Harvard International Astronomical Union. The center informed the global
academic community of the news in a respective circular.
In different times, international scientists had named
five minor planets in honor of our eminent scientists in recognition of the
latter’s marvelous merits. By acknowledging the pioneers, the scholars entitled
them Uzbekistania, Avicenna, Ulughbek, Beruni and Khorezmi.
The latest discovery in Uzbekistan was made at Maydanak
Astrophysics Observatory of the Astronomy Institute, located high in the
mountains 120
kilometers from Samarqand. The success was the outcome
of the hard work by young scientists Bahodir Hafizov and Aleksei Sergeyev. They
exposed the minor planet during one of the cool nights of October 2007 while
monitoring the sky with the principal observatory telescope AZT-22 with a
unique mirror of one-and-a-half meters in diameter. The researchers noticed a
faintly luminous object moving in the background of still stars. They
determined its coordinates and calculated the preliminary elements of the
orbit. The data was sent to the Minor
Planet Center
who informed the lucky astronomers that that object had not been listed in
catalogs, and was given a preliminary number. It took them two more years of
scrupulous research to specify the orbit of the unknown item to have the Minor
Planet Center confirm the discovery of the Uzbek scholars.
The minor planet Samarqand rotates around the Sun
between Mars and Jupiter orbits as part of the so-called asteroid belt.
Asteroids are solid astronomical bodies containing iron, chondrites and some
other chemical compounds. Studying asteroids has been of paramount scientific
value because their substance, unlike that of major planets, did not
participate in evolutionary processes and remained as they were in the early
periods of the solar system’s formation.
Asteroids are blocks of protoplanetary substance. They
should have become a basis for the formation of planets, but that did not
happen. Science fiction authors even named it Faeton and wrote a lot of works.
One of them was about the smart civilization on the planet that led to the
destruction of the planet by its unreasonable actions. However, according to
modern scientific idea, such planet has never been existed since it just
couldn’t form.
“There are numerous fabulous works on danger of the
collision of a big asteroid with Earth,” noted Shuhrat Egamberdiyev. I bring
the opinion of the specialists participating in Tashkent international scientific conference
to the notice of readers: there is no danger of collision of our planet with a
big asteroid or comet in the soonest time.”
The conference participants informed that Maydanak
observatory locating in the center of Eurasian continent, with its excellent
astronomical climate to observe cosmic bodies, is planned to be included into
the network of ground observatories studying the Wilson-Harington comet.
Japanese scientists are going to send their exploring spacecraft there. Uzbek
scientists together with their colleagues from the National Astronomical
Observatory of Japan continuously monitor asteroids in the Maydanak
observatory.
