What are asteroids made of?
Most of these asteroids feature large volumes of carbon molecules along with the harder usual rocks and metals.
The composition of an asteroid can be very similar to the carbonaceous chondrite meteorites that occasionally fall on this planet. It happens to be why these meteorites usually are chippings, smashed off in the course of collisions between asteroids.
On April 19, Asteroid 2014 JO25 to fly safely passing Earth, around 1,090,733 miles away from Earth, which roughly translates to 4.6 times the distance between the planet and the Moon.
At the same time on April 19, the comet PanSTARRS is going to make a flyby with its closest approach to Earth, in a very secure range of 109 million miles. A faint fuzzball in the sky when it was discovered in 2015 by the Pan-STARRS NEO survey group using a telescope over the summit of Haleakala, Hawaii.
The comet features brightened considerably due to a recent outburst as well as is now noticeable during the dawn sky with binoculars as well as a small telescope.
Asteroid 2014 JO25, about 2000 feet wide was discovered in May 2014 by astronomers at the Catalina Sky Survey near Tucson, Arizona-a project of NASA’s NEO Observations Program in a joint venture together with the University of Arizona.
Asteroid 2014 JO25 closest flyby in 400 years
Modern measurements by NASA’s NEOWISE mission point out that this asteroid is approximately 2,000 feet in dimensions. Its surface area is approximately 2 times as reflective as that of the moon. At this point hardly any else is known about the object’s physical properties, even though its trajectory is well known.
The asteroid will get close to Earth coming from the direction of the sun and can become visible in the night sky just after April 19.
It’s expected to brighten to about magnitude 11, when it may be visible in small optical telescopes for one or two nights before it fades given that the distance from Earth instantly heightens.
Right after analyzing the orbit of Asteroid 2014 JO25, astronomers aware the April 19 encounter could be the closest this asteroid has get to Earth for at the very least 400 years and will be its closest approach for at least the next 500 years. There is no danger as the space rock’s orbit is well known, report said. Image of “What are asteroids made of?” / NASA
