On October 12, which asteroid is flying towards the earth. Comet ISON is more dangerous than they say and the United States knows it. Meteorite fragments will be drawn in a lottery in Chelyabinsk

A house-sized asteroid passes close to Earth. NASA scientists say there is no risk of impact, but the flyby gives them a chance to test their asteroid warning systems. A global network of telescopes will closely monitor the object.

It is estimated to be between 15 and 30 m, which is relatively small. However, even space rocks on this scale are dangerous if they strike. NASA scientists who have spent the last two months tracking this new rocky visitor say their calculations show it will clean up Earth safely and pose no threat.

Instead, they will use this close approach to referee future potential strikes. This will help them clarify how asteroids are tracked and enable them to test international communications systems. Dr Chodas said that although the risk of being hit by an asteroid was small, it would be wise to plan ahead.

Where did the Chelyabinsk meteorite come from and why it was impossible to detect it

"NASA's search programs are getting better and better at finding asteroids," he explained. The first priority was to find large asteroids. So far, NASA research has found that 95% of asteroids are one kilometer or larger - those that could cause a global catastrophe.

Now we are working our way to smaller ones - 130 m in size and larger ones - and by about 30%. This one is small - we're not trying to find all of these sizes. It's just a convenient asteroid for us to practice our tracking techniques on. He added that if an asteroid was discovered heading for Earth, scientists would consider different methods to prevent disaster.

If we had enough warning time - five or ten years - then we could do something about it, especially if it was on the small side. “We could go up and move it, change the speed of our years forward, and that would be enough to move it off the collision course.”

However, as it begins to approach us this summer, large telescopes will be used to reconstruct its exact trajectory and narrow down the uncertainty. Best image: The green line indicates the apparent motion of the object relative to the Earth, and the bright green marks are the location of the object at approximately one-hour intervals. The blue arrow indicates the direction of the Earth's motion, and the yellow arrow points to the Sun.

For the first time, a scientific experiment has measured the Earth's ability to absorb neutrinos - particles smaller than atoms that scale throughout space and through us by the trillions every second at nearly the speed of light.

The main difference is that we know that this asteroid is happening in contrast to the event that unfolded in Chelyabinsk.

Watch a live feed of the asteroid passing through Earth via the Sloo Observatory's broadcast stream. It is outside the orbit of geostationary satellites. Fortunately, astronomers are confident that the asteroid is harmless will pass the Earth and there will be no reason for alarm. Similarly, Makoto Yoshikawa of the Japan Aerospace Exploration Agency said: The distance is very short. But this distance does not mean a collision.

Gyorgy-Rice of the University of Texas says. Although it has a large uncertainty in orbit, it is much smaller than the radial uncertainty, so it simply changes the time of the closest passage. Although Earth's safety is sufficiently certain for this passage, Earth's gravity will significantly alter the asteroid's trajectory before exiting the Earth-Moon system.

This "asteroid flyby," or close approximation to a better phrase, will provide an opportunity for professional astronomers to test their detection and tracking abilities near Earth objects. The object's brightness is expected to peak at level 9 at its closest approach, so it will also be visible to amateur astronomers.

Potentially hazardous asteroids

Potentially hazardous asteroids are identified based on parameters that measure the asteroid's potential to threaten close approaches to Earth. An asteroid four times the size football field, will fly past Earth on Halloween night. This event shows how important it is to look for rocks in space.

For some people, Halloween is the perfect scary time. This nice 400 meter feature will be included. Experts can say almost nothing about the physical properties of the asteroid and can only deduce basic data from previous observations. A diameter of more than 400 meters is a rough estimate, as is the case for any object for which we do not have any details, for example.

Once an object is detected by radar, we can gather more accurate information about its size. A significant portion of these objects have not yet been discovered. This program is based on new automated telescope technology in Europe. Objects of this size are often detected in automated observations, says Koszny. However, due to their enormous size, they are usually visible when they are still quite far away, at distances of up to 2.5 times the distance between the sun and the earth. This asteroid is an exception because it was discovered shortly before its approach to Earth.

This distance is eight times less than the distance between the Earth and the Moon, Russian astronomers warn. Asteroid rates -3.66 on the scale of Palermo, with a probability of 1 in 630 impacts over the next hundred years. Would you like to talk about this for a moment?

The combined gravitational pull of the Sun and Moon on bodies of water found on our planet generates a wave, the propagation of which, observed from locations on the shores, leads to the cyclical rise and fall of sea level. Anciently it was considered a kind of "breath of the sea", as if water was periodically swallowed displaced by large underwater cavities, this level variation can be calculated using celestial mechanics methods, but contributions such as those related to winds and meteorological conditions are not easily predictable.

Visibility maps were provided by their author, Dr. H. van Gent from the Institute of Mathematics at Utrecht University, whom we thank for his cooperation. Van Gent maintains a website about improving the lunar visibility forecast. Moon - Christmas: Before dawn on October 7, a waning crescent moon appears at the crossroads of the Constellation Cancer, not far from the Nativity chair.

Moon - Venus: begins a long series of interesting morning alliances with the protagonists of three planets visible before sunrise. In the early hours of October 8, the swinging crescent of the Hawk, entering the constellation Leo, approaches Venus and the star Regulus. Moon - Venus - Mars - Jupiter: The next day - October 9 - The Moon, now reduced to a thin spit, continues its journey into the constellation Leo, where it "surpassed" Venus, approaching Mars and Jupiter.

Moon - Mercury: October 11 The Moon, an increasingly thin sliver near the Moon phase, completing its crossing of the Constellation Leo, overtaking Venus, Mars and Jupiter, approaches Mercury. Moon - Saturn: October 16, the crescent moon, now waxing, is visible in the evening shortly after sunset in the constellation Scorpio along with Saturn.

Venus - Jupiter: A series of conjunctions in the morning sky continues. October 26 - turn of a close encounter between the two brightest planets: Venus and Jupiter meet in the constellation Leo; just below Mars.

Venus - Mars - Jupiter: Before dawn on October 28, three planets appear on the eastern horizon, still in the constellation Leo, in this order: from top to bottom, Jupiter, Venus and Mars. Moon - Pleiades: On October 29, the lunar disk is in the constellation Taurus: in this case, the Moon is not very close to the Pleiades. The most important development is the occultism of Aldebaran, the brightest star in the constellation of the Bull, described in the next paragraph.

Thursday, October 29, late at night, we will be able to observe an important astronomical event that once again amazes us and leaves us fascinated. The Moon's altitude will vary between the beginning and end of 38° and 50°, so it will be very high and visible in the night sky. The event will be visible from all over Italy, just look south to appreciate it.
