The "Death Comet" Will Pass By Earth Just After Halloween

"The trajectory of 2015 TB145 is well understood. At the point of closest approach, it will be no closer than about 300,000 miles -- 480,000 kilometers or 1.3 lunar distances. Even though that is relatively close by celestial standards, it is expected to be fairly faint, so night-sky Earth observers would need at least a small telescope to view it."

"We found that the object reflects about 6 percent of the light it receives from the Sun. That is similar to fresh asphalt, and while here on Earth we think that is pretty dark, it is brighter than a typical comet which reflects only 3 to 5 percent of the light. That suggests it could be cometary in origin ? but as there is no coma evident, the conclusion is it is a dead comet.”
