Mercury is the smallest actual planet of the eight comprising the solar system. It is actually smaller (but more massive) than the moons Ganymede and Titan. Mercury has about 5.5% of the mass of Earth.
Before 24 August 2006, Pluto considered the smallest planet of our solar system. On that date, the IAU modified the definition of "planet" and Pluto no longer qualified. It was reclassified as a "dwarf planet." There are a number of smaller objects, including dwarf planets, asteroids, and Kuiper Belt objects (past the orbit of Neptune).
Sizes of the Planets (largest to smallest)
Jupiter
Saturn
Uranus (3rd largest)
Neptune (3rd most massive)
Earth
Venus
Mars
Mercury
The smallest star that we know of is called: OGLE-TR-122b at 0.12 solar radii (that's 167,000 km).
Pluto is the smallest planet in the solar system.
There is only one star in our Solar System - the Sun. So it's the youngest and oldest star.
The sun is the only star in the solar system.
The smallest stars in the solar system is called the Orions Arm.
The youngest, and only, star in this solar system is the sun
Mercury is the smallest major planet in our solar system. The smallest dwarf planet is Ceres.
the answer is mercury
The planet Mercury.

yes ,the universe is made up of our solar system and there are systems within systems that keep going on and on. The universe is made up of countless numbers of stars. These stars form huge groups of stars called galaxies. Within these galaxies are solar systems. Our solar system is but one of billions.
They are called Core Burning Stars the smallest one is OGLE-TR-122b.
Smallest or largest, there is only one star in our Solar System - The Sun.

No. Even the smallest collection of stars would be far larger than even the largest solar system.

One cannot say for sure if it is the smallest planet in space, but it is the smallest planet in our Solar System.
There is only one star in our solar system; it is called The Sun.
in cases of stars, the answer is unknown due to the are of the solar system. in cases of planets, the answer is either Pluto or Mercury.
We can't say, exactly. Since a solar system is just a system of bodies orbiting around a star (a star with a system orbiting it is called a sun), and there are billions of stars in every galaxy, we don't have nearly enough information to make even an educated guess about solar system size rankings.
Yes. There are no stars in the Solar System besides the Sun but there are over billions of stars out of our Solar System.
Our solar system is part of the Orion Arm of the Milky Way galaxy.
