It's finally here - the sequel to "Star Size Comparison." Notes:
Kepler-10c is an exoplanet (a planet outside the Solar System) orbiting the star Kepler-10, located around 568 light-years away in the constellation Draco. Its was discovered through the Kepler space telescope in May 2011.
Sirius is the brightest star in the night sky. At a distance of 8.6 light-years, the Sirius system is one of Earth's nearest neighbours.
Pollux is an orange-hued evolved giant star about 34 light-years from the Sun in the constellation of Gemini. It is the closest giant star to the Sun.
Arcturus, in the constellation of Boötes, is the fourth-brightest in the night sky, and the brightest in the northern celestial hemisphere. It is relatively close at 36.7 light-years from the Sun.
Aldebaran is a red giant star about 65 light-years from the Sun in the zodiac constellation Taurus. It is the fourteenth-brightest star in the night sky.
Rigel is the seventh-brightest star in the night sky and the brightest star in the constellation of Orion. Its distance from the sun is about 860 light-years.
Antares, in the constellation of Scorpius, is the fifteenth-brightest star in the night sky. Its distance from the sun is about 550 light-years.
Betelgeuse is the eleventh-brightest star in the night sky. Its distance from the sun is about 700 light-years.
UY Scuti is a red supergiant in the constellation Scutum. It is one of the largest known stars by radius. Its distance from the sun is about 5100 light-years.
A star is a massive, luminous ball of plasma held together by gravity. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth. Other stars are visible from Earth during the night when they are not outshone by the Sun or blocked by atmospheric phenomena. A star shines due to thermonuclear fusion of hydrogen in its core releasing energy that traverses the star's interior and then radiates into outer space.
