Canopus (-0.72), Vega (0.03), Arcturus (-0.04), Procyon (0.38), Hadar (0.61), Aldebaran (0.85), and Achernar (0.46) in order from brightest to dimmest apparent magnitude.
The bright stars were observed and recorded by the Babylonians, those people who were ruled by Nebuchadnezzar and others. As well as taking the Jews to Babylon they invented the idea of dividing a circle into 360 equal degrees, which they used to describe the positions of objects in the sky, so they were perhaps the first scientists.
No, the size of a rainbow is not related to the size of the Earth. The size of a rainbow is determined by the angle of light refraction and the position of the observer relative to the arc of the rainbow, not the size of the Earth.
About the size of a pea

Achernar (Alpha Eridani), sometimes spelled Achenar, is the brightest star in the constellation EridanusIt has a spectral class of B3V which means it's temperature is 10,000-30,000 K and it's colour will be blue white.
Achernar, the ninth-brightest star in the night sky, is estimated to be around 58 million years old. This makes it a relatively young star compared to others in the galaxy. Its high rotational velocity causes it to be slightly flattened at the poles.
