A small asteroid or comet has become the first ‘visitor’ from beyond our solar system
It is smaller than a quarter of a mile (400 meters) in diameter, but A/2017 U1 is perhaps the first known object from outside the solar system that has made its way inside. Some more data-crunching and analysis is still needed to confirm the interstellar nature of the object, which could be a comet or an asteroid. A/2017 U1 made its closest approach to the sun Sept. 9 but was discovered Oct. 19 by Rob
Two Asteroids think they are a Comet
The Hubble Space Telescope has discovered something truly unique – a pair of orbiting asteroids that are behaving like a comet. A group of astronomers used the NASA/ESA telescope to observe the system known as 288P in September 2016, just before it made its closest approach to our Sun. To their surprise, 288P is not a single asteroid, as previously thought, but a pair of orbiting space rocks with very unusual characteristics. The asteroids are

Ancient Asteroid Generated the Hottest Temp Ever Recorded on Earth
When an asteroid smashes into the Earth things get pretty toasty. A 17 mile-wide crater in Canada was home to what scientists say is the hottest temperature ever recorded in Earth’s crustal rock, a whopping 4,300 degrees Fahrenheit. They didn’t just stick a thermometer in there, of course, the crater is some 36 million years old. Instead, researchers from Curtin University in Australia looked to the rocks. Embedded in the crater walls were crystals
