New satellite discovered recently

According to the websites descopera and iflyscience,NASA astronomers have announced that they have discovered a new moon in our solar system .

It is a cosmic object found near the dwarf planetMakemake - located intheKuiperBelt. The announcement strengthens the hypothesis that most of the dwarf planets have moons except Pluto which is a particular situation.TheKuiperBelt extends from the orbit of Neptune to 50 astronomical units away from the Sun. Until the year 2000, itwas believedthat the belt contained only planet Pluto, the Charonsatelliteand several comets, but recently other cosmic bodieshave been discovered.

These types of satellites - like the one discovered recently nearEris(a dwarf planet)have been discovered in the past.

The Hubble telescope discovered the new satellite

Recently, the Hubble telescope has identified a new satellite in the structure of theKupierBelt. Itwas namedS / 2015 (136472) and more simply - MK2. Very little information aboutMK2 has been known until now. It is estimated thatMK2has a diameter of about 160 kilometers and has a brightness of 1,300 times weaker thanMakemake. However, its orbit characteristics are still unknown.

Identifying composition.

Once the orbit has been measured,Makemake'smass will be calculated usingthe fact thatthe orbital period depends on the distance between the two cosmic objects and on their mass. Since theMakemake'sdiameter is already known - about 1500 km - this willshowwhat density the satellite has andthereforewhat its composition is. Astronomers are eager to know how different it is from Pluto, and not justin terms ofsize.

Shell of frozen methane.

It is already knownthe fact thatMakemake, like Pluto, has a shell composed of frozen methane, but nobody knows what lies beneath this layer. Plutois locatedat a distance of about 39.5astronomical unitsfrom the Sun, while Makemakeis positionedat 45.7astronomical units. The orbit will also be an indicator of the origin ofMK2.

Warmer surface temperatures.

Makemakehas puzzled astronomerspreviouslybecause it seemed to have on its surface warmer areas thanthe ones observed so far in the other smaller planets.

However, it seems that these regions were, in fact, thedetection of MK2 made in the telescopes which could not clearly distinguish the two objects. This confusionwas madebecause the satellite has a warmer temperature on its surface than the planet around which it orbits.
