mars is a small planet
No. A white dwarf is the collapsed remnant of the core of a low to medium mass star. It has a mass comparable to that of a star, but is about the size of a small planet.
Because the gravity would be heavier on Jupiter, even though the planet is mostly a gas giant with a small iron core. The iron core is still larger than Earth I believe. The answer is, because of the increased gravity due to the increased size of the planet. Care to venture a guess as to how much you'd weigh on the sun?
Some stars are bigger than the planet like the sun but some are small. The size varies.
There isn't a typical size planet
With a radius of 3396km, the planet Mars is about the same size as the inner and outer core of the earth (which is around 3490km radius in total).

The size and fluidity of the core of the planet.
The Earth's inner core is increasing in size as the planet cools.
How can it's core be bigger than it's size?? Mercury has a much larger core than any other planetary body compared to it's total size. It's core is estimated to have a radius of about 1,800 km whilst the radius of the planet is about 2,440 km.

Dwarf planets are not a special type of planet. A small planet is later classified a dwarf planet. The only characteristic that makes it a dwarf planet is the size. Your question should be why are some planets small?

small.
Once upon a time, the answer would have been a confident, "Jupiter," but recently almost a thousand "exoplanets" have been discovered, many of which are bigger. From what we know of planet formation, we THINK these are gas giants, planets with vast atmospheres and small, rocky nucleii.
