Mars Trojans may be part of a planet that was destroyed long ago
By Rebecca Boyle Mars has an asteroid entourage, with nine so-called Trojans trailing in its wake. Now it seems these travelling companions all had the same violent beginning: as the innards of a mini-planet, eviscerated in a violent collision. Some remnants may even have been incorporated into the material that became Mars. Trojans are distinct from the asteroids found in the asteroid belt, which begins about 101 million kilometres past Mars and stretches toward Jupiter.
NEOShield-2 Participation at ACM 2017 in Montevideo
The series of conferences “Asteroids, Comets, Meteors” focuses on the research of small Solar System bodies. The series constitutes the leading international meeting in this field. The first three conferences took place in Uppsala, Sweden in the 1980's, and afterwards they were organized every ~3 years all over the world. In the last editions, a sequence was started where the conference has been held in different continents. In 2017, ACM was held in South America,
Asteroid 2014 JO25 to Fly Safely Past Earth on April 19, 2017
2014 JO25, a relatively large near-Earth asteroid discovered nearly three years ago will fly safely past Earth on April 19, 2017 at a distance of about 1.1 million miles (1.8 million kilometers), or about 4.6 times the distance from Earth to the moon. Although there is no possibility for the asteroid to collide with our planet, this will be a very close approach for an asteroid of this size.

Is a Colorado earthquake related to dinosaurs extinction impact?
by Seismological Society of America Researchers have found signs of fault displacement at well-known rock outcrops in Colorado that mark the end-Cretaceous asteroid impact that may have hurried the extinction of the dinosaurs. They will present their results in a poster at the 2017 Seismological Society of America's (SSA) Annual Meeting. Norm Sleep of Stanford University and colleagues suggest that the impact, which occurred near the Yucatán Peninsula of Mexico, could have generated massive seismic
