Scientists were less than expected by OmwamwiIn the new study, data was given about the first war object that he identified who was flying through the Solar system, writing Chronicle.info with reference to the Telegraph.
Omwamwi was first registered in October 2017 with Pan-STARRS 1 telescope in Hawaii during the inspection of the underground asteroids. Further comments carried out by a number of telescope in the ground and the "Hubble" space telescope show that the surface of the object reflects sunlight. Large variations in the brightness of the object led to the conclusion that Omwamwi has a long shape and is likely to not exceed 800 meters long.
Recently in the Astronomical Journal, a new study by which of Omwamwi conferences is not quite accurate.
The "Spitzer" space telescope traces asteroids and comets using infrared energy, or heat, after radiation. It can provide more accurate information on the size of the object or the optical observations or reflect sunlight. The fact that Omwamwi was too big for "Spitzer", set some limitations in total surface area.
Using three different models that provide different assumptions about the composition of the object, Omwamwi is a spherical diameter limited to 400, 140 and 100 meters. There is a great difference in the results based on assumptions about the Omwamwi composition, affecting how it can see "Spitzer" at a certain size.
"Omwamwi was full of starters of the first day, so we can not wait to show" Spitzer, "said lead author of the study, Professor David Trilling, University of North Arizona. – The fact Omwamwi is too small for "Spitzer" to be able to register, in fact a valuable result. "
New size limits correspond to recent research, conducted by the Marco Micheli astronomer with ESA. According to them small changes in speed and direction, Omwamwi was found as a result of defaults. In other words, the allocation of the surface of the gas acted as a small accelerator.
Omwamwi proved to be so much less common in the Solar system. The conclusion is that he has experienced defects, suggesting that he has frozen gases as a comet.
"Our study also suggests that Omwamwi can be 10 times more reflective (it has a higher albedo – Along with it) than comets in the Solar system," said Trilling.
Maybe the comet may change during its "life". When coming to the Sun, its ice is heated up and turning gas, dust sweeping and surface dirt, showing more reflecting ice.
Omwamwi traveled through inter-billion space millions of years away from stars that could "renew" the face. But it may be heated enough to go to the Sun for about five weeks before opening it.
