For all that matters Yes. It is a near perfect sphere, with an oblateness estimated at about 9 millionths which means that its polar diameter differs from its equatorial diameter by only 10 km (6 miles).

Space is thought to be mostly flat on large scales, as predicted by the theory of general relativity. However, the universe may curve on cosmological scales due to the presence of mass and energy, resulting in a three-dimensional shape that is difficult to visualize, which can be different from a simple sphere.
We do not know if "space" itself has an discernible shape, or what that shape might be. Spherical or roughly spherical is one good choice.
However, some mathematical models of the universe suggest that "space" is more toroidal. A "torus" is a doughnut-shape.
The sun is an imperfect sphere like the earth and the moon which are oblate spheroids but the sun is more flatter at its geographic poles and bulge more at the equator because it is made up of plasma.
The exact shape of the Universe on a large scale is not known yet. As far as we can see (roughly, the "observable Universe"), the Universe seems to be fairly flat, meaning that if it does curve back on itself like a hyper-sphere, or some other shape, the entire Universe is much, much bigger than the part that we can see.
No, Some are "potato" shaped such as Phobos and Deimos, the Moons of Mars. Also, planets such as Jupiter and Saturn, perhaps even Uranus, Neptune, Pluto, and Eris may have moons that have not been discovered yet that are not round. It is quite common, as any cloud of debris without sufficient mass and gravity to pull itself into a spherical shape will be irregular. Ceres is considered a dwarf planet, in the asteroid belt, and even though asteroids cannot be considered moons, some may be irregularily shaped.
No. For a start, it is somewhat flattened, due to its rotation. The diameter from pole to pole is about 1/297 less than the diameter through the equator.
There are three models for the possible shape of the universe, one is spherical. The three concepts provide for a spherical universe, a hyperbolic universe, or a flat universe
No. Some moons are too small for their gravity to make them spherical. Two prime examples are Phobos and Deimos, the two moons of Mars.
The planet Earth is a spherical object that orbits the sun in space.
In space, flames become spherical due to a lack of gravity to pull the flames upwards. The absence of gravity causes the flame to burn in all directions uniformly, creating a spherical shape. This phenomenon is known as a "cool flame" and is different from flames on Earth, which are affected by gravity.
The Moon. It is a spherical object in space that reflects sunlight.
The spherical shape of Sputnik made it more aerodynamic and stable when launched into space. This design helped in reducing air resistance during launch and allowed for better weight distribution of internal components.
The definition of a spherical coordinate system is a coordinate system for 3D space where the position of a point is specified by three separate numbers. These three numbers are the radial distance, polar angle, and azimuth angle.
