Astronomers find first carbon-rich asteroid in Kuiper Belt
Washington, May 10: Astronomers have discovered an unusual carbon-rich asteroid in the Kuiper Belt -- the first of its kind to be confirmed in the cold outer reaches of the solar system.
This object, designated 2004 EW95, likely formed in the asteroid belt between Mars and Jupiter and has been flung billions of kilometres from its origin to its current home in the Kuiper Belt, the study said.
The researchers found that the asteroid's reflectance spectrum -- the specific pattern of wavelengths of light reflected from an object -- was different to that of similar small Kuiper Belt Objects (KBOs), which typically have uninteresting, featureless spectra that reveal little information about their composition.
"The reflectance spectrum of 2004 EW95 was clearly distinct from the other observed outer Solar System objects," explained lead author Tom Seccull of Queen's University Belfast in Britain
"It looked enough of a weirdo for us to take a closer look," Seccull added.
Theoretical models of the early days of our solar system predict that after the gas giants formed they rampaged through the solar system, ejecting small rocky bodies from the inner solar system to far-flung orbits at great distances from the Sun.
In particular, these models suggest that the Kuiper Belt -- a cold region beyond the orbit of Neptune -- should contain a small fraction of rocky bodies from the inner solar system, such as carbon-rich asteroids, referred to as carbonaceous asteroids.
The new study, published in The Astrophysical Journal, presented evidence for the first reliably-observed carbonaceous asteroid in the Kuiper Belt, providing strong support for these theoretical models of our solar system's troubled youth.
After measurements from multiple instruments at European Southern Observatory's Very Large Telescope (VLT), the team of astronomers was able to measure the composition of the object.
The results suggest that it originally formed in the inner solar system and must have since migrated outwards.

Allahabad HC orders police protection to married couple apprehending 'honour killing'
Prayagraj (PTI): The Allahabad High Court has granted protection to a married couple who expressed fear that they may be killed by the woman's family.
The order was passed by a division bench comprising Justice JJ Munir and Justice Tarun Saxena on March 25.
"No individual can make an 'honour issue' out of a consenting adult marrying a person of their own choice. It is the state's duty to protect the life, limb, and property of such persons even against their own family members," the bench said.
The court was hearing a petition filed by Prachi Agrawal and her partner, who sought relief in connection with an FIR filed under Section 87 of Bhartiya Nyaya Sanhita (BNS) for kidnapping, and abducting or inducing a woman to compel her marriage.
The couple submitted that they married at an Arya Samaj temple and possessed a marriage registration certificate issued under the Uttar Pradesh Marriage Registration Rules, 2017.
The petitioners alleged that the woman's family members were averse to their marriage and lodged a bogus FIR against them.
The couple further submitted a joint affidavit expressing apprehension of an honour killing by the woman's family.
The court said that a prima facie case was made out and issued notice to the private respondent and granted two weeks to file a counter-affidavit.
Meanwhile, as an interim measure, the court granted the petitioners protection from arrest.
The court also explicitly ordered the woman's family members and relatives not to harm the petitioners, enter their matrimonial home, or establish contact with them directly or through any electronic means.
The bench directed the Aligarh senior superintendent of police to ensure that no harm comes to the couple and posted the matter for hearing on April 8.
