"MORE ASTEROID NEWS: Now that 2014 RC has passed, another even weirder asteroid is approaching Earth's neighborhood. 2002 CE26 is a binary asteroid consisiting of a primary space rock 3.5 km in diameter and a secondary approximately one-tenth as wide. What's weird is, radar data suggest that the secondary space rock might have a moon of its own. Alberto Quijano Vodniza of the University of Narino Observatory in Colombia photographed the triple system streaking through the constellation Pegasus on Sept. 2nd:

At closest approach on Sept. 9th, 2002 CE26 will be 18.4 million km (0.123 AU) from Earth. That is relatively far away, but because of the asteroid's large size, it is still possible to obtain meaningful data from the flyby. NASA astronomers will be pinging the system using the Goldstone radar in the Mojave desert. The Goldstone team says "we should be able to get coarse-resolution images of the primary. Echoes from the secondary will be weak and on the edge of detectability."

They also encourage experienced amateur astronomers to monitor the flyby: "This object should reach 14th magnitude while at favorable solar elongations, so it should be an excellent target for lightcurves. Lightcurves might detect the signature of at least one satellite and could help refine the orbital period."

Big Asteroid Is Heading Close to Earth
April 08, 2017 - A relatively large asteroid will cross Earth's orbit around the sun this month. Astrophysicists and astronomers say there is no chance of a collision, but it will be the closest flyby of an asteroid that large for at least another 10 years.
Asteroid 2014 JO25, discovered three years ago, is about 650 meters (2,100 feet) in diameter, 60 times as large as the small asteroid that plunged into our atmosphere as a meteor and exploded over the Russian city of Chelyabinsk in 2013. That blast was felt thousands of kilometers away and caused havoc on the ground, damaging more than 7,000 homes and offices and injuring 1,500 people. Asteroid 2014 JO25's pass by Earth on April 19 will be a near miss, cosmically speaking. The U.S. space agency NASA said no one should worry: "There is no possibility for the asteroid to collide with our planet, [but] this will be a very close approach for an asteroid of this size."

The Minor Planet Center of the International Astronomical Union classifies 2014 JO25 as a "potentially hazardous asteroid." (Astronomers classify asteroids as "minor planets"; when they pass close to Earth they are termed "near Earth objects.") An animation of the intersection of Earth's orbit and that of 2014 JO25, prepared by the Jet Propulsion Laboratory, a unit of the California Institute of Technology, makes it look like an awfully close call, but the hard facts are more reassuring: At its closest point, the asteroid will be about five times as far from Earth as the moon is, more than 1.75 million kilometers away (1,087,400 miles).

The passage of asteroid 2012 DA14 through the Earth-moon system in February 2013 is depicted in this handout image from NASA. This asteroid, at 150 feet in diameter, was puny compared with the visitor we're about to get: Asteroid 2014 JO25 is about 2,100 feet in diameter, but there's no chance of a collision with us.​

Although the asteroid is expected to be twice as reflective as our moon, it will be difficult to spot in a night sky filled with stars, and certainly not without help. Scientists say the sort of telescope amateur astronomers use should be adequate to pick out the space rock as it whizzes across the sky at 120,000 kilometers per hour (74,500 mph). EarthSky.org, a website that follows developments in the cosmos and throughout nature in general, has posted an article with detailed information to help sky-watchers find the asteroid on April 19, and for a day or two afterward. Professional astronomers also will be tracking 2014 JO25 closely. Puerto Rico's Arecibo Observatory, an extremely powerful radio telescope center, will study the asteroid for five days.

After all, it's not often that something as big as this comes along, even a couple of million kilometers from home. NASA says 2014 JO25 hasn't been this close to Earth in the past 400 years, and it will be at least 500 years before it comes back for a repeat close encounter with our planet. Asteroids actually pass close to Earth fairly often, but it's their size that matters. Asteroid 2017 GM made one of the closest passes by Earth ever seen — 16,000 kilometers (9,900 miles) above sea level — less than a week ago, on April 4. Little notice was taken, however, because that chunk of space rock was about the size of a small car.

I have incredible and astounding news. The planet wide interferometer was turned on only a couple of days ago and will take several months to compile the data. Astrophysicists don't know the diameter of the supermassive black hole at the center of our Milky Way galaxy and should give this info as well as see the event horizon. Possibly proving Einstein wrong.
 
When the bollard falls to Earth it will land in the Pacific Ocean between Hawaii and California. Supercomputers figured that out years ago but the asteroid has to hit the sweet spot to come back two years later and impact Earth. Californians should move to Nevada because of the giant tsunami so big and never recorded in history or prehistory.
