Astronomers have gotten their closest look but at an unusually formed asteroid orbiting the solar within the asteroid belt situated between the orbits of Jupiter and Mars.
The unusual asteroid, named Kleopatra, was not too long ago imaged in probably the most element thus far utilizing the European Southern Observatory’s Very Massive Telescope (VLT). The picture beneath exhibits the asteroid from totally different angles, revealing its two lobes linked by a middle portion with an total form like a bone.

“Kleopatra is really a singular physique in our Photo voltaic System,” said the lead creator of a brand new examine on the asteroid, Franck Marchis, an astronomer on the SETI Institute. “Science makes a number of progress because of the examine of bizarre outliers. I believe Kleopatra is a kind of and understanding this advanced, multiple-asteroid system can assist us be taught extra about our Photo voltaic System.”
To know the form of Kleopatra, the researchers used the Spectro-Polarimetric Excessive-contrast Exoplanet REsearch (SPHERE) instrument on the VLT to seize it from totally different angles after which created a 3D mannequin of its form. They seen that one lobe is somewhat bigger than the opposite, and in whole its size is round 170 miles.
One other fascinating tidbit about this asteroid is that it has two moons orbiting it. Their orbits are advanced as a result of asteroid’s odd form, however with these modeled the researchers may use this data to calculate the asteroid’s mass, which turned out to be significantly lower than beforehand estimated.
Future research of Kleopatra will use the upcoming Extremely Large Telescope (ELT) to have a look at it in much more element. The adaptive optics system of this new telescope will use a deformed mirror to minimize the distortion brought on by the ambiance, permitting it to see distant objects just like the asteroid in sharper focus.
“I can’t wait to level the ELT at Kleopatra, to see if there are extra moons and refine their orbits to detect small modifications,” stated Marchis.
The analysis is printed within the journal Astronomy & Astrophysics.
