The North Star, Polaris, is not exactly at true North.  It's 41 minutes of arc away.  That's farther than the width of the full Moon.  But Polaris can be used to align your telescope to exactly true north.  It's exactly right twice a day - and any planetarium software can tell you when.  This is used to align permanently mounted telescopes.

Much was made about how fast New Horizons left the Earth and flew past Jupiter.  When will it overtake Voyager 1?  Never.  Voyager 1 got a bigger gravity assist by flying closer to Jupiter.  So, it's going faster.

What is the planet that comes the closest to Earth?  Venus.  The rule is that planets closer to the Sun are closer to each other.  The gaps get bigger and bigger.  But at the moment, Mercury is the closest planet to the Earth.  Mars and Venus are on the other side of the Sun.  Well, so is Mercury, but remember, Mercury is closest to the Sun...  This is a little unusual.
