A new study on Phaethon could finally clear the secret of why this weird asteroid appears blue



The asteroid Phaethon reflects light in the most unusual way and astronomers believe that they know some of these reasons for it …

Astronomers have closely watched the near-Earth asteroid Phaethon and believe that he has finally cracked the secret of why this one Asteroid reflects the light in such a strange way and has a blue hue.

According to Phys.org Astronomers of the Seoul National University, the National Astronomical Observatory of Japan (NAOJ), the Chiba Institute of Technology and other international universities have the asteroid with the help of the 1.6-m Pirka Researched telescopes in Japan at the Nayoro Observatory to analyze the polarization of light on phaethone and published a new study based on their observations.

Phaethon was originally discovered in 1

983 and on December 16, 2017, it sped past Earth, which is only 6.4 million miles away. This is the planet closest to our planet Year 2093 is rolling around. After the asteroid was so close last year, astronomers discovered that there was a massive void in the center of Phaethon.

After observing how this asteroid reflects light after observing it at various angles, the new study indicates much less light can be reflected off the surface of Phaethon than previously thought.

There could be many reasons for this and include the presence of an unknown material lurking on the asteroid, the material being extremely porous. The surface of phaethone can also be quite dark, which is another plausible reason for the lack of light reflected from its surface.

How the Report Daily Mail reports when light is reflected off the surface of an asteroid and bounces off Another area before astronomers can see the light when light is scattered across more than one surface would cause highly polarized light, so Dr. Ito, the chief astronomer of the latest research.

"If the albedo is lower than previously thought, that would reduce the effectiveness of multiple scatters, so that highly polarized light that was reflected only once would dominate."

If Phaethon is closest to the Sun, his Surface temperatures of 1,000 degrees reach Cels Ius. This could cause part of the surface of the asteroid to form coarse grains.

The DESTINY + probe will be launched by the Japan Aerospace Exploration Agency in 2022 and will fly images of Phaethon so that astronomers can get a closer look at the geology of this asteroid and get a better idea of ​​what its surface actually looks like which would give a clear picture of why it reflects light as it is.

The new research on the polarization of light on the asteroid phaethon has been published in Nature Communications .
