You can become an astronomer.  This is one of the hot topics in astronomy right now, and quite a bit of effort is being put into it by professional astronomers.  In the meantime you can use your spare CPU cycles to help check radio signals from other stars for signs that they may have been produced with the inetent of contacting us through the SETI@home project.  The rpgram runs as a screen saver, and has been around for a number of years now.\n\nAs far as Voyager 2, it is just under 80AU away (80 times the distance from the earth to the sun), in the direction of the constellation Telescopium.

The axis, and therefore, poles, gravitational pull is slowly changing. (Therefore changing due Norths position.)  That's alot of observant Sailors.

Thank you very much for the link you gave. I read this news yesterday night on Yahoo. I have forgotten about this until you have remind me. Thank you again.  \nIs there any other way for us to view it other than using a telescope? I don't have a telescope.

well there are two answers.  The pole is actually shifting as we speak albeit to such a minor degree that we would never notice during our lifetimes.  The present 'north star' polaris was not always the 'north star' and in the future a new 'north star' will take it's place.  There have been drastic pole shifts possibly resulting from the passage of an enormous comet or asteroid within or close to the orbit of the moon.  When this occurs, drastic changes take place in a short span of time.  It is theorized that the break-up of pangaea into the continents was caused by a sudden pole shift.  From Straight Dope :Geologist Jean Andrews of Columbia University has found evidence to suggest that 180 million years ago the poles were displaced about 22 degrees from their present alignment, with the North Pole located on the northern coast of what is now the Soviet Union.

I don't know the name, I think it just has a number.\n\nIt is about 1,000,000 km away and is a captured asteroid about 1km across.  It is irregular in shape.  It is in an unstable orbit and will eventually leave the Earth's orbit and enter solar orbit.

The satelite was not one but two.\n\n"The twin Voyager 1 and 2 spacecraft continue exploring where nothing from Earth has flown before. In the 25th year after their 1977 launches, they each are much farther away from Earth and the Sun than Pluto is and approaching the boundary region -- the heliopause -- where the Sun's dominance of the environment ends and interstellar space begins. Voyager 1, more than twice as distant as Pluto, is farther from Earth than any other human-made object and speeding outward at more than 17 kilometers per second (38,000 miles per hour). Both spacecraft are still sending scientific information about their surroundings through the Deep Space Network (DSN). "\n\nIt has nothing to do with them dark matter...the speed is relevantly low and they are not in "free fall".\nThere is no friction at all due to "The areas between strands of galaxies are completely empty.  You would have to travel Hundreds of miles to find just one atom. "( http://www.kidsastronomy.com/universe.htm )\n\nBut you can get more info from the official website  of nasa.\nhttp://voyager.jpl.nasa.gov/mission/mission.html

use v^2 =  GM/r\n\nv = root GM/2r\n\norbit = 2 pi r\n\nfor part 2 use suvat equations, s=vu+.5at^2 etc and it should fall out

744 million miles at the closest point

One cannot provide solution without the longitude of local station...\nIt shall be atleast 2500 miles away...

Use the North Star like you would a compass.\n\nThe North Star is a title of the star best suited for navigation northwards. A candidate must be visible from Earth and circumpolar to the north celestial pole. The current one is Polaris. It is the star at the end of the "handle" of the Little Dipper asterism in the constellation Ursa Minor.\n\nThe North Star has been historically used by explorers to determine their latitude. At any point north of the equator the angle from the horizon to the North Star (its altitude) is the same as the latitude from which that angle was taken. For example, the angle to the North Star for a person at 30° latitude will be about 30°.\n\nPolaris has a visual magnitude of 1.97 (second magnitude). In 3000 BC the faint star Thuban in the constellation Draco was the North Star. At magnitude 3.67 (fourth magnitude) it is only one-fifth as bright as Polaris. The first magnitude star Vega will be the North Star by AD 14,000.\n\nCurrently, there is no South Star as useful as Polaris; the faint star σ Octantis is closest to the south celestial pole. However, the constellation Crux, the Southern Cross, points towards the south pole.

Oscar. You have written too much. This 125m tower stuff does not matter compared to r=6.38*10^6. Why is this talk about 1.00 km and angle theta? See what “zipper” above says. Besides I answer your last question << Why is the trajectory of the cannonball not parabolic?>>. Why should it be if both you and Newton demand it to be circular? Assume that V1 of cannonball is the 1st cosmic speed corresponding to a circular track. Let V2 be > than V1, then you receive an oval track. Take V3 > than V2, then the track may become parabolic, so that cannonball would never return back to the cannon to linger out among planets and stars. If you are intrigued calculate a set of velocities and corresponding orbits of the cannonball. If cannon is not available consider a football! I like your inventive wits – to be honest!
