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.

ED attaches fresh assets in PMLA case against Reliance Group; total attachment over Rs 10K cr
New Delhi (PTI): The Enforcement Directorate has attached fresh assets worth Rs 1,120 crore as part of its money laundering probe against the companies of Reliance Group chairman Anil Ambani, officials said.
Eighteen properties, including the Reliance Centre in Mumbai's Ballard Estate, fixed deposits, bank balance and shareholding in unqouted investments of Reliance Anil Ambani Group have been provisionally attached under the Prevention of Money Laundering Act (PMLA), they said.
Another set of seven properties of Reliance Infrastructure Ltd, two properties of Reliance Power Ltd, nine properties of Reliance Value Service Private Ltd, fixed deposits in the name of Reliance Value Service Private Ltd, Reliance Venture Asset Management Private Lt, Phi Management Solutions Private Ltd, Adhar Property Consultancy Pvt Ltd, Gamesa Investment Management Private Ltd and investments made in unquoted investment by Reliance Venture Asset Management Private Ltd and Phi Management Solutions Private Ltd have also been attached, they said.
The ED had earlier attached properties worth over Rs 8,997 crore in the bank fraud cases related to Reliance Communications Ltd (RCOM), Reliance Commercial Finance Ltd, and Reliance Home Finance Ltd.
The total attachment in the case against the Reliance Group is now Rs 10,117 crore.
