* Sagittarius is a constellation: It's a grouping of stars that appear close together from Earth, but are spread across vast distances in space. There's no single point representing the entire constellation.
* The Moon orbits Earth: Its distance from Earth constantly changes.
* The Earth orbits the Sun: The Earth's position changes, influencing the apparent position of the Moon and stars.
Therefore, you cannot measure a straightforward distance between Sagittarius and the Moon.
Instead, it's more accurate to say that Sagittarius and the Moon are both celestial objects visible from Earth. Their relative positions in the sky change throughout the year due to the Earth's and Moon's orbits.
