    Distances and angles

    Distances and angles

    Even if we don’t know the distance to an object, angles are easy to measure. By total coincidence, the Sun and Moon happen to subtend nearly the same angle from Earth at the moment. Therefore, we can have eclipses.


    Astronomy and cosmologies week 1 spring 2005

    In this week’s Space and Time workshop, you’ll use your hands to find angles. Also discover the field of view of your binocs.


    Astronomy and cosmologies week 1 spring 2005

    2p radians = 360 degrees

    1 degree = 60 arcminutes

    1 arcminute = 60 arcseconds

    1 AU = 93 million miles = 150 million km

    1 parsec ~ 3 light years
