Q. What should its parallax be? Is it probable that this distance was determined using basic parallax methods? Why did you respond as you did?

A. 1,600 light years = 490.6 parsecs Parallax in seconds of arc= 1/490.6 = 0.002" However, hipparcos (a probe sent out to measure parallaxes) measured Deneb's parallax as close to 0.001" Because such a small measure is at the limit of what the probe could measure, there is a lot of uncertainty: Deneb could be anywhere from 2,000 to 7,500 light years. The value quoted in Wikipedia (1,000 parsec) is based on the approximate value of 0.001". This is as good an estimate as you can get using what we know so far.

A. Cygnus is an easily-recognisable Northern Hemisphere constellation, one of Greek astronomer Ptolemy's original 48, The cross-like pattern of its main stars suggests the outline of a flying swan. A less common alternative name for the constellation is indeed the 'Northern Cross'. Cygnus has more than its fair share of double and variable stars, and it boasts the first-discovered 'black hole'.

A. Maplestory is much more balance than before with less kill stealing problems. There are more maps and empty channels to train. Cygnus knights can only be level 120 max and you get 6 points per level. There is no bandit or cleric class for cygnus knights. Thunder breakers has replace bandits. For each 10 levels of your main character, your cygnus knight gets a +1 weapon attack, magic attack, avoid, and acc. I would recommend night walker or dawn warrior. Night walker are assassin class. They get to have flash jump at second jump and they do the highest damage. It's quite expensive to spent all the dexless equipments and luck equipments. They are quite fast and strong. Dawn warrior are the second most popular. They now have somewhat… [cont.]
