An ‘interstellar object’ comes calling

The Hindu  

‘Oumuamua, the first interstellar object discovered in the solar system in October 2017, is moving away from the sun faster than expected. The original observations indicated a 230-metre-long, elongated, tiny object whose colour was similar to that of a comet and whose extremely eccentric orbit too led the International Astronomical to classify it as one. “We think that ‘Oumuamua may vent unusually large, coarse dust grains,” she added. The team has speculated that the small dust grains that adorn the surface of most comets may have, in ‘Oumuamua’s case, eroded during its journey through interstellar space, and that only the larger dust grains remained.
