Arrange the following in increasing order of size: 1. Earth 2. Andromeda 3.…

Comparing objects across drastically different physical scales — from a human-made satellite to an entire galaxy — means anchoring each one against its own known measurement: a satellite in metres, a moon or planet in thousands of kilometres, a star in over a million kilometres, and a galaxy in light-years, where a large galaxy such as Andromeda spans hundreds of thousands of light-years.

1. Artificial Satellite — even a large satellite such as the ISS spans only about 109 metres end to end, the smallest scale here.

2. Moon — Earth's natural satellite, diameter about 3,474 km.

3. Earth — diameter about 12,756 km, larger than the Moon.

4. Sun — diameter about 1.4 million km, over 100 times Earth's diameter.

5. Andromeda Galaxy — spans well over 200,000 light-years, making it larger than the Sun (and everything else in the list) by many orders of magnitude.

Ranking each item by its own measured scale gives the increasing-size order: Artificial Satellite, Moon, Earth, Sun, Andromeda — matching "5, 4, 1, 3, 2".
