Astronomy Crossword - Interesting Facts

To help put you in the mood to solve this Astronomy Crossword puzzle, here are a few interesting facts about astronomy from

  • The Asteroid Ceres Is Pretty Big. The largest asteroid in our solar system — Ceres — has a diameter of 580 miles (940 km).

    In 1801, Giuseppe Piazzi discovered Ceres in the main asteroid belt between Mars and Jupiter. The asteroid contains roughly one-third of the entire asteroid belt's mass!

    Ceres is the only "dwarf planet" inside Neptune's orbit and the largest object in the main asteroid belt.

  • Polaris and Vega Take Turns. The North Star changes every 26,000 years.

    Earth's axis goes through a process known as "precession" — a change in the orientation of a rotating body's rotational axis. Because of that, our perception of the north gradually shifts to different stars over a 26,000-year cycle.

    Our ancestors began understanding astronomy millennia ago and used the North Star for navigation. Several thousand years ago, Vega was the North Star, and it will gain that status again in around 12,000 years.

    However, in 26,000 years, Polaris will return to its original position as the Earth's polar star.

  • A Light-Year Is More Than a Trillion Miles. Scientists from various fields of astronomy use "light-years" to measure the distance between celestial objects. A light-year is the distance light travels in an Earth year.

    Light travels at a speed of 186,000 miles per second (300,000 km/s), and one light-year is about 6 trillion miles (9 trillion km).

    Since light needs so much time to reach us, whenever we are looking at celestial objects, we see them in the past. For example, the Sun is 8 light minutes away from us, so each time we look at it, we always see it as it was 8 minutes ago.
