Mercury is roughly spherical in shape, like most other planets. Its shape is determined by its gravity, which pulls the planet's material into a compact, rounded form.
Gravity pulls the asteroids into spheres when they get big enough.
As with all planets it is an oblate spheroid
Every planet has a center of gravity, anda sphere is the mostgravitationally stable shape for a planet to have.
All planets are 'round' because of gravity. With the formation of the Solar System, gravity gathered gas and dust into clumps which became larger and eventually planets. The collision of these pieces caused planets to become hot and molten and gravity pulled the molten material towards the planet's centre in the shape of a sphere. The planets cooled and remained spherical
The inner planets have a spherical shape. In fact all planets are more or less spherical.
Planets are all spherical.
The inner planets (Mercury, Venus, Earth, Mars) in our solar system are all roughly spherical in shape due to their gravity compressing their material into a spherical form. They lack the mass to maintain a more irregular shape like some larger moons or asteroids.
Spherical
Approximately "spherical".
The sun is a sphere, while planets are generally spherical in shape due to gravity pulling their mass evenly in all directions. Some planets have slight deviations from a perfect sphere due to rotation or geological activity, but they are still predominantly spherical in shape.
The force of gravity pulls objects toward their center, causing them to form a spherical shape over time. Planets and other large celestial bodies are able to overcome any irregularities and form into spheres due to gravity's influence on their mass and density.

Since all of the planets, and moons, and stars seem to have a spherical shape, it is possible that the universe may be a sphere.
