Only the 50 cent coin, known as yotin, is square shaped. All other coins are round. For a while the 5 florin note was replaced with a square coin but it's now minted as a round coin.
Post (pillow shaped) and maybe Quaker (round) , but I haven't seen them in a while.

a plant cell has a large, oval shaped bubble looking vacuole, while the animal cell's is small and round, like a sphere
binary stars are two stars that orbit each other while supernovas and novas stars are stars that explode when it runs out of fuel

All of the planets are in the same atmosphere. All of the planets are unique. All of the planets are considered planets. All of the planets have moons. All of the planets are named after a mythical person or thing.
the stars "move" because of the way earth spins so then the constellations and stars look like they're moving but it realy is the earth that moves. In other ways the stars stay ware they are while the earth is spinning
Other yellow-white stars like our sun do exist. The color of a star depends on its temperature. The coolest stars are red while the hottest are blue. Our sun falls in the middle of this range.
