The stars are folded as follows:
1, prepare a colored note.
2. Tie a knot at one end of the colored paper.
3. Cut off the extra paper at the short end.
4. Fold the long paper around the shape of the five-pointed star.
5. Stuff the extra paper in.
6. Pinch the five corners of the five-pointed star into a solid, so that a five-pointed star is completed.
The shape of the stars in reality:
Without external force, under the action of universal gravitation, all objects tend to gather towards the center. The most concentrated result is spherical. Although a star is solid on the surface, it is possible to transform it into a sphere, because solids are also deformable and solid particles are movable.
The energy activity inside the star makes the shape of the star irregular. However, the stones in the mountains roll down from the heights due to the gravity of the stars, and the rivers carry the sediments from the heights to the low-lying oceans (rivers also flow due to the gravity of the stars). These are all examples of concentration to the center, which make the star change from irregular to spherical.
If the interior of the star stops moving, it is likely that the star will become a very standard sphere (except for centrifugal force and gravity of other celestial bodies) after many billions of years.
Many asteroids, because of their small mass and low gravity, are generally composed of hard solid rocks, and it is difficult to complete the process of moving to the center under the action of their own gravity, so their shapes are grotesque, oval and rod-shaped. ...
But for various reasons, the star is just an ellipsoid close to a sphere.
