    Hi guys! I have a question, really it will be good if you can help me.

    when it was discovered that some stars are greater than another one?
    And the distance was greater than another?

    I'm not sure what you mean by one star being greater than another one, unless you mean larger or brighter.

    I'm pretty sure that from the First time amn started looking at the sky he noticed that some stars were brighter than others. The first attempt to quantify this can be dated back to Hippachus in 190 BC. He developed the brightness scale that we still use today.

    The first measurement of star distance was made in 1807 by Freidrich Bessel.
