> Czech astronomers have made a number of important discoveries recently.
> Earlier this year they discovered a Nova, which is a star temporarily
> emitting a great amount of energy and light, and solved a question which
was
> puzzling astronomers around the world, that is whether one very bright
> object was or was not actually two stars. Several days ago, an unknown
> asteroid was observed from the Klet observatory in South Bohemia. More
from
> Pavla Horakova.

> Astronomers Milos Tichy and his wife Jana who work at the Klet observatory
> discovered an unknown asteroid moving close to the earth last week. The
> object, about 70 metres in diameter, passed our planet at a distance of
3.5
> million kilometres, which is relatively close by astronomical standards.
We
> know of around 900 such objects, known as near-earth asteroids. They
present
> a potential threat to the earth because they interfere with the earth's
> orbit. The one discovered last week has a similar size to the object which
> caused the Tunguz catastrophe in Siberia in 1908. Czech observatories
> participate in a joint programme of monitoring these near-earth asteroids.
> Petr Harmanec is the director of the Astronomical Institute of Charles
> University.

> "This programme has immediate consequences for people. In case there is
> indeed some large asteroid which could one day fall into the earth's
> atmosphere, this would be a catastrophe of global proportions. If this
> monitoring allowed us to know the exact orbit of such a body well in
> advance, the present rocket technology would allow us probably to do
> something against it. It means to change the trajectory of such a body
when
> it is still far away from the earth. You know that one satellite was sent
to
> the Eros asteroid and which then became an artificial satellite of this
> asteroid, therefore the technology is indeed there."
>
> The discovery made by the Tichys was confirmed on the same night by
> astronomers from New Zealand and Canada. The asteroid was given the
> international designation 2002 LK and is now moving safely away from the
> earth. Czech astronomers are celebrating their new success and they hope
the
> new law reducing light pollution in the country will help to improve
> conditions for observing and thus enable more such discoveries.
