* By absolute brightness: The Sun is by far the brightest object in our sky. It's a star, and it's the closest star to Earth.
* By apparent brightness: This refers to how bright an object appears from Earth. Here's the order:
* Sun: The Sun is the brightest object in our sky, as we see it every day.
* Moon: The Moon reflects sunlight, making it appear bright, but it's much fainter than the Sun.
* Stars: Stars are incredibly far away, so they appear as tiny points of light. Even the brightest stars are much fainter than the Moon.
So, the Sun is the brightest object in our sky by both absolute and apparent brightness.
