> The distances between the Sun and its planets vary greatly. For example, the distance from the Sun to Mercury is about 36 million miles, while the distance from the Sun to Pluto is about 3.6 billion miles. The size of the Sun is about 864,000 miles in diameter, which means that the distance from the Sun to its planets is much greater than the size of the Sun itself.
Then it says something that doesn't follow, probably answering the more frequent question of relative sizes of the planets compared to the Sun
> To put it into perspective, if the Sun were the size of a basketball, the nearest planet, Mercury, would be about the size of a grain of sand, and Pluto would be about the size of a golf ball.
