Stars with larger masses have stronger gravity; this results in more pressure; which in turn makes the star hotter. As a result of the higher temperature, they will shine brighter, and burn their fuel much faster.
That Is a difficult question because what are you asking about? Most planets in our solar system are larger than all oceans combined as well as most stars. I think all the continents combined is smaller that the oceans combined.
The official unit for mass in science (and elsewhere), of course, is the kilogram. In astronomy, for ease of comparison, the masses of stars, and even galaxies, are often expressed in "solar masses", meaning multiples of the mass of our Sun.
The stars with the shortest lifetimes are massive stars, specifically those with masses greater than about 8 times that of the Sun. These stars burn through their nuclear fuel at an incredibly rapid rate, leading to lifespans of only a few million years. In contrast, smaller stars, like red dwarfs, can last for billions of years. The rapid consumption of fuel in massive stars ultimately leads to their explosive deaths as supernovae.
The "corpses" of stars may be white dwarves, neutron stars, or black holes (and perhaps "quark stars", but this is still very speculative). In general, the least massive stars - which also tend to be smaller - will become white dwarves. These are much smaller than "active" stars, but much larger than neutron stars or black holes. The more massive the star, the SMALLER will the white dwarf be - due to the increased gravity. Our Sun has a diameter of 1.4 million kilometers; other stars can be several times smaller, or larger - but a white dwarf only has a diameter of a few thousand kilometers. More massive stars become neutron stars, which have a diameter of 20-30 km - and an immense density, similar to that of an atomic nucleus. The most massive stars end up as black holes. Here, the only "diameter" that can be observed from the outside is that of its event horizon, which is directly proportional to the black hole's mass. A black hole the mass of the Sun would have a Schwarzschild radius (the radius of its event horizon) of about 3 km; therefore its "diameter" would be about 6 km. A black hole a billion times the mass of the Sun would have a Schwarzschild radius of 3 billion kilometers.
Dwarf stars are NOT "so much Bright", the smaller the star is (provided it is on the main sequence) the less intrinsically bright it is.
Yes, there are even stars smaller than earth. Most are collapsed ancient stars that have become neutron stars and have masses slightly larger than our sun currently has.

Because larger stars burn their hydrogen faster than smaller ones.
Smaller stars last longer.
larger stars have longer lives, because as stars burn they are slowly burning up fuel and begin to cave in on themselves. the larger, the more fuel, the more fuel, the longer lasting.
Approximately 10% of stars are larger and more massive than the Sun. Most stars in the universe are smaller, with a significant portion being red dwarfs, which are much less massive. The distribution of stellar masses typically follows the Salpeter distribution, where lower-mass stars are more common than higher-mass stars.
Most stars are smaller than the Sun, but those that are larger can be a lot larger.
The smaller stars
The smaller a star the longer it lives. Smaller stars can live up to 200billion years, while a supergiant only lives about 10 billion years. Cooler stars live longer because they don't burn as much energy as a hotter star, while the larger the star, the shorter its lifespan

No. Stars are many times larger than planetesimals.
Most stars are smaller than the sun, falling into the red dwarf category.
