Executive Orders are controversial because they allow the President to make major decisions, even law, without the consent of Congress. This, of course, runs against the general logic of the Constitution -- that no one should have power to act unilaterally.
Voyager 1 has since become the fastest and most distant man-made object in the Universe, travelling at around 61,500km/h at a distance of 17.6 billion km from the Earth. Perhaps most incredible of all, NASA is still in communication with it, despite radio signals taking 16 hours to reach it. Image Â© NASA.
The nearest star, Proxima centauri is 4.22 light years away. Light travels at a speed of 186, 000 miles/sec. = 186,000 x 3600 x 24 x 365 = 5.865 trillion miles per light year. To travel the distance of one light year, Voyager will have to travel for 5.865 trillion miles/(35,000x 24 x 365) = 19,130 years.(Another way to calculate is speed of light/sec divided by speed of voyage/sec = 186,000/(35,000 X 3600) = 19,130 years). For 4.22 light years = 4.22 x 19,130 = 80,730 years.s of August 10, 2007, Voyager 2 is at a distance of around 83.5 AU from the Sun, traveling outward at roughly 3.3 AUs a year. A light year is 63,240 AU-the nearest star is Proxima Centauri at 4.3 light years (therefore 271,932 AU away). Voyager is already 83.5 AU from the sun, so Prox. Cent. would be 271,847 AU away.
