5. Pluto is about 4,000,000,000 miles (4 billion, or 4 x 109 miles) away from Earth, but is only about 2,000 miles in diameter. How big an angle (in degrees) will this planet make in a telescope? Degrees How big an angle is this in arc-seconds? Convert this angle in degrees to the smaller unit of arc-seconds following the examples in Table A. If your telescope can resolve objects about 2 arc seconds in size, will Pluto be visible? Comment! Answer: Answer: arc seconds Comments:
