An explosion occurs when the timescale for the energy release by some process is much shorter than the timescale on which a system can adjust to damp the energy release process. In the present day Sun, nuclear fusion is a very slow process: on average it takes many billion years for a proton to fuse with another. This timescale is quite temperature dependent, so you might have thought the centre of the Sun might heat up quickly, leading to a runaway "explosion". However, an increase in temperature leads to an increase in pressure that would expand the Sun, reducing the core density and temperature and decreasing the rate of nuclear fusion again. The timescale for the Sun to react in this way is just millions of years, so this acts like a thermostat that keeps the reactions under control.
The population of the Netherlands is <span>densely packed in a small area. In fact, the Netherlands is the most densely populated region in Europe, and one of the most densely populated in the world. With a population density of 488 people per km^2, the Netherlands has a total population of 16.5 million people.</span>
It means that the government, instead of free market, determines what is sold and how much it costs.

Answer:
Their gravity helps make life possible.
Explanation:
The Jovian planets are also known as gas giants and have had more of an impact on Earth than most Earthlings probably realise. During the formation of the solar system, these planets captured large planetesimals as moons and allowed the inner solar system to form less violently.
The gravitational pull of these massive planets also drew comets laden with ice from the outer reaches of the solar system towards the dry rocky worlds in the center. It was largely due to this slingshot process that Earth received its oceans.
Finally, the Jovian planets protect the inner planets today by deflecting asteroids and comets that might otherwise penetrate into the inner solar system and collide with Earth.
