Question: On 11 July 2011, Neptune completed its first full barycentric orbit since its discovery in 1846, although it did not appear at its exact discovery position in the sky, because Earth was in a different location in its 365.26-day orbit. Because of the motion of the Sun in relation to the barycentre of the Solar System, on 11 July Neptune was also not at its exact discovery position in relation to the Sun; if the more common heliocentric coordinate system is used, the discovery longitude was reached on 12 July 2011.
Is there an answer to this question: When did Neptune complete it's last barycentric orbit since it's discovery?

Answer: unanswerable

Question: The final has never been contested by two teams from outside the top division and there have only been eight winners who weren't in the top flight: Notts County (1894); Tottenham Hotspur (1901); Wolverhampton Wanderers (1908); Barnsley (1912); West Bromwich Albion (1931); Sunderland (1973), Southampton (1976) and West Ham United (1980). With the exception of Tottenham, these clubs were all playing in the second tier (the old Second Division) - Tottenham were playing in the Southern League and were only elected to the Football League in 1908, meaning they are the only non-league winners of the FA Cup. Other than Tottenham's victory, only 24 finalists have come from outside English football's top tier, with a record of 7 wins and 17 runners-up: and none at all from the third tier or lower, Southampton (1902) being the last finalist from outside the top two tiers.
Is there an answer to this question: What was the last finalist from inside the top two tiers?

Question: A common misperception is that the Supreme Court is the only court that may determine constitutionality; the power is exercised even by the inferior courts.

Is there an answer to this question: Which courts' decisions, other than Supreme Court, are binding across the country?

Answer:
