A few hours the Earth will pass close to discovered two days ago an asteroid 2012 TV, and now we expect even closer flyby of asteroid, discovered by an US survey Pan-STARRS. Object that has the temporary designation P104imJ was discovered on October 4. Within 8 days, on October 12 (4:45 UT), the asteroid will flyby at least 97,000 km from the Earth. According to preliminary data, the size of the object can be from 15 to 30 meters.
Very interesting the lead time for discovering of such objects. Amateur, 40-cm telescope, was discovered larger object in just 2 days before it’s close approach, while powerful, professional 1.8-meter telescope, discovered the object of more than a week before it’s close approach to our planet.
The promising all-sky survey PanSTARRS (Panoramic Survey Telescope & Rapid Response System), having finally started regular observations, discovered its first comet October 6th! The short-period comet of the Jovian family received the designation P/2010 T2 (PANSTARRS) and, in principle, nothing special stands out about this comet. The comet’s period is approximately 13.2 years; its orbital inclination is small, on the order of 8 degrees. The comet will reach perihelion at the end of July 2011, and the new comet’s minimum distance from Earth will be October 14th (4.5132 a.u.). The comet’s brightness will not exceed 20th magnitude.
After the future comet was placed on the MPC Confirmation page, observations of the new object were carried out by two large telescopes – the Kitt Peak 2.3 meter reflector, and the one-meter telescope of the Japanese observatory Bisei Spaceguard Center.
