With Asteroid 2017 DS109 We've had our 8th Potentially Hazardous Asteroid pass by Earth in under 1 Lunar Distance. So that's over 1 scary asteroid per week. AND NOW. We have 20 newfound asteroids passing by Earth in the next 17 days. So that's a very interesting uptick trend. ya? God bless everyone, Strange Days Indeed.

Designated 2017 EA, the asteroid made its closest approach to Earth at 6:04 a.m. PST (9:04 a.m. EST / 14:04 UTC) at an altitude of only 14,500 kilometers (9000 miles) above the eastern Pacific Ocean. At its closest point, this asteroid was 20 times closer than the Moon; it then quickly moved into the daytime sky and can no longer be observed by ground-based telescopes. 2017 EA was originally detected only 6 hours before closest approach by astronomers at the NASA-funded Catalina Sky Survey, near Tucson, Arizona. It was observed by several other observatories before it passed into the Earth's shadow just before closest approach. Even though 2017 EA was tracked for only a single day, its orbit is now known quite accurately. Computations by CNEOS indicate that the asteroid will not approach our planet this close again for at least a hundred years. Asteroids are minor planets, especially those of the inner Solar System. The larger ones have also been called planetoids. These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disc of a planet and was not observed to have the characteristics of an active comet. As minor planets in the outer Solar System were discovered and found to have volatile-based surfaces that resemble those of comets, they were often distinguished from asteroids of the asteroid belt.[1] In this article, the term "asteroid" refers to the minor planets of the inner Solar System including those co-orbital with Jupiter. There are millions of asteroids, many thought to be the shattered remnants of planetesimals, bodies within the young Sun's solar nebula that never grew large enough to become planets.[2] The large majority of known asteroids orbit in the asteroid belt between the orbits of Mars and Jupiter, or are co-orbital with Jupiter (the Jupiter trojans). However, other orbital families exist with significant populations, including the near-Earth objects. Individual asteroids are classified by their characteristic spectra, with the majority falling into three main groups: C-type, M-type, and S-type. These were named after and are generally identified with carbon-rich, metallic, and silicate (stony) compositions, respectively. The size of asteroids varies greatly, some reaching as much as 1000 km across. Asteroids are differentiated from comets and meteoroids. In the case of comets, the difference is one of composition: while asteroids are mainly composed of mineral and rock, comets are composed of dust and ice. In addition, asteroids formed closer to the sun, preventing the development of the aforementioned cometary ice.[3] The difference between asteroids and meteoroids is mainly one of size: meteoroids have a diameter of less than one meter, whereas asteroids have a diameter of greater than one meter.[4] Finally, meteoroids can be composed of either cometary or asteroidal materials.[5] Only one asteroid, 4 Vesta, which has a relatively reflective surface, is normally visible to the naked eye, and this only in very dark skies when it is favorably positioned. Rarely, small asteroids passing close to Earth may be visible to the naked eye for a short time.[6] As of March 2016, the Minor Planet Center had data on more than 1.3 million objects in the inner and outer Solar System, of which 750,000 had enough

Will an Asteroid hit Earth in 2017? The DATA looks kind of Scary right now. #okc #news #wth
