Yes, it does. The core is much denser and hotter than, say, the chromosphere or the photosphere. A link is provided below
Due to the pressure of the outward layers, it has a greater density at the center; less density outside.
The next planet after Saturn moving outward from the Sun is Uranus.
Earth
Uranus
The core of the Sun is considered to extend from the center to about 0.2 to 0.25 solar radius. It is the hottest part of the Sun and of the Solar System. It has a density of up to 150,000 kg/m³ (150 times the density of liquid water) and a temperature of close to 15,000,000 kelvin (by contrast, the surface of the Sun is close to 6,000 kelvin). The core is made of hot, dense gas in the plasmic state. The core, inside 0.24 solar radius, generates 99% of the fusion power of the Sun.
If you are starting at the Sun and moving outward, Venus is after Mercury.
Outward. Energy is converted in the Sun's core (center), through nuclear fusion, and producing heat; from there, it gradually moves outward.
The next planet after Saturn moving outward from the Sun is Uranus.
The core of the Sun is considered to extend from the center to about 0.2 solar radii. It has a density of up to 150,000 kg/m3 (150 times the density of water on Earth) and a temperature of close to 13,600,000 kelvins (by contrast, the surface of the Sun is around 5,800 kelvins).
In equilibrium.
The corona varies in shape and extends outward from the Sun for sever million kilometers. It's also the the Sun's outermost layer.

Only in the very center of the sun can the nuclear fusion take place - that is the only part of the sun where heat and pressure are both high enough. As you move outward from the center, the pressures and temperatures both drop below the level necessary to cause fusion. Hence, the star has a state of equilibrium.
Uranus
It is Saturn
The density of the Sun is 1.408×103 kg/m31408 kg/m3. This is the AVERAGE density; the density in the core is greater, the density in the photosphere is less than this.
