As Big As the Sun

This artist's concept shows the smallest star known to host a planet. The planet, called VB 10b, was discovered using astrometry, a method in which the wobble induced by a planet on its star is measured precisely on the sky.

The dim, red star, called VB 10, is a so-called M-dwarf, located 20 light-years away in the constellation Aquila. It has only one-twelfth the mass, and one-tenth the size, of our sun. The planet is a gas giant similar in size to Jupiter but with six times the mass. Though the planet is less massive than its star, the two orbs would have a similar diameter.

VB 10b orbits its star about every 9 months at a distance of 30 million miles.

Tan grande como el Sol

Este artista, concepto muestra el menor estrella conocida de acoger un planeta. El planeta, llamado VB 10b, fue descubierto usando astrometría, un método en el que el uso inducida por un planeta en su estrella es medido precisamente en el cielo.

La dim, estrella roja, llamado VB 10, es un llamado M-enana, situado a 20 años luz en la constelación Aquila. Tiene un solo-12 la misa, y una décima parte del tamaño, de nuestro sol. El planeta es un gas gigante similar en tamaño a Júpiter pero con seis veces la masa. Aunque el planeta es menos masiva de su estrella, los dos orbes tendría un diámetro similares.

VB 10b órbitas su estrella aproximadamente cada 9 meses a una distancia de 30 millones de millas.
