List of the smallest stars by star type. The red dwarf stars are considered the smallest stars known, and representative of the smallest star possible. Brown dwarfs are not massive enough to build up the pressure in the central regions to allow nuclear fusion of hydrogen into helium.
These lists contain the Sun, the planets, dwarf planets, many of the larger small Solar System bodies (which includes the asteroids), all named natural satellites, and a number of smaller objects of historical or scientific interest, such as comets and near-Earth objects.
Red dwarfs are considered the smallest star known that are active fusion stars, and are the smallest stars possible that is not a brown dwarf. More information Star name, Date ... Close. Notes. Applying the Stefan–Boltzmann law with a nominal solar effective temperature of 5,772 K: .
Mercury (0.31–0.59 AU from the Sun) [D 6] is the smallest planet in the Solar System. Its surface is grayish, with an expansive rupes (cliff) system generated from thrust faults and bright ray systems formed by impact event remnants. [92]
Watch on. Our Sun is very small, compared to some stars. The planets are as dust compared to blue and red Giant of our universe. This video on YouTube, the relative sizes of the planets and stars are made of the smallest to the largest.
29 mar 2024 · Mercury is the smallest planet in our solar system. Mercury is a little more than one-third the width of Earth, and has an equatorial diameter of about 3,032 miles (4,880 kilometers). Mercury is the closest planet to the Sun, orbiting at an average distance of 36 million miles (58 million kilometers).
Mercury is the closest planet to the Sun and is the smallest planet in our Solar System after Pluto was reclassified as a dwarf planet in 2006. Mercury circles around the Sun in an egg-shaped orbit. Thanks to its egg-shaped orbit, Mercury is also the closest planet to Earth, on average.
