Japanese astronomers discovered two giant heavenly bodies with giant telescopes with two telescopes only 28 cm |

Using two telescopes weighing 28 cents, which you can buy from the internet, Japanese astronomers discovered celestial bodies that are only 1.3 km away from Cooper Belt on the edge of the solar system.

The Kuiper Belt is located on the outside of the orbit of Neptune's solar system (about 30 astronomical units from the Sun) and is spread over microplanets with a diameter of several kilometers to thousands of kilometers called the Cobo Celestial Body (KBO). Asteroids in the inner solar system received more sunlight and experienced more collisions. Appearances have changed in the last billions of years, but the celestial bodies in the cold cypress band have been thrown into the outer waves in the early hours and have not made the sun. That's why astronomers are the best subject to study the original solar system.

The new horizons of NASA just fly the wider than the 33-mile belt of the Ultima Thule asteroid belt and the high-quality photographs that go back, show that Ultima Thule looks like a little snowman with a reddish tint.

Unfortunately, we still do not know very little about the celestial bodies of heaven. Even the stellar telescope (also known as Subaru Telescope), which has an extremely orbiting dwarf planet, can not directly observe small heavenly bodies that are only a few kilometers wide. A team led by the astronomer of the Japanese National Observatory, Ko Arimatsu, decided to take advantage of the occult phenomenon to find microplanes.

Occultation refers to the darkening phenomenon that the heavenly body passes between the other heavenly body and the observer. In general, the visual area of ​​the concealer is larger than that of the hidden man. The research team placed two 28-cm-long Celestron binoculars on the roof of the school and spent 60 hours monitoring about 2000 stars between June 25, 2016 and August 1, 2017. Data analysis found that during the observation period only the luminosity of one of the stars decreased, that the object passed the star and the estimated width of the building was only 1.3 km.

The discovery may support the hypothesis of Russian astronomer Viktor Safronov, the microplanter of the micronutrient, which concerns the formation of small dust particles by constant precipitation and bonding, where the diameter of the small celestial body reaches about 1 km. In the big hours you can attract each other by gravity and prototype the lunar scale faster.

But maybe even worse, he only spent about 500,000 NT, which is much less than 0.3% of the big international program budget, but he found small objects that were not visible even with large telescopes. Hey, if you are also an amateur astronomer who has only a little money to spare, can he help you find an old planet with micro-planets?

The new team article was published in the journal Nature Astronomy.
