Stellar Contradiction: Solar Systems Like Ours May Be Quite Rare

Chinese space debris heading towards International Space Station, Russian scientists say. Roscosmos said that according to preliminary data the debris fragment will "fly close" to the manned orbiting laboratory on November 12 at around 4 a.m. Moscow time, or 8 p.m. ET on November 11.

The observed object corresponds to a mass of 3-5 Earth masses orbiting the Sun at a distance of about 210-240 AU. If the interpretation is correct, then it is definitely an object in our own solar system that can be classified as a super-earth.
