A G-type main-sequence star (spectral type: G-V), also often, and imprecisely, called a yellow dwarf, or G star, is a main-sequence star (luminosity class V) of spectral type G. Such a star has about 0.9 to 1.1 solar masses and an effective temperature between about 5,300 and 6,000 K (5,030 and 5,730 °C; 9,080 and 10,340 °F ).
G-type main-sequence stars are main-sequence stars (luminosity class V) of spectral type G. Subcategories. This category has the following 3 subcategories, out of 3 ...
Of the main-sequence star types, stars more massive than 1.5 times that of the Sun (spectral types O, B, and A) age too quickly for advanced life to develop (using Earth as a guideline). On the other extreme, dwarfs of less than half the mass of the Sun (spectral type M) are likely to tidally lock planets within their habitable zone, along with ...
The main sequence is visible as a prominent diagonal band from upper left to lower right. This plot shows 22,000 stars from the Hipparcos Catalog together with 1,000 low-luminosity stars (red and white dwarfs) from the Gliese Catalogue of Nearby Stars. In astronomy, the main sequence is a classification of stars which appear on plots of stellar ...
Category. : Main-sequence stars. Wikimedia Commons has media related to Main-sequence stars. Main-sequence stars, also called dwarf stars, are stars that fuse hydrogen in their cores. These are dwarfs in that they are smaller than giant stars, but are not necessarily less luminous. For example, a blue O-type dwarf star is brighter than most red ...
The Sun is classed as a G2 star, meaning it is a G-type main-sequence star, with 2 indicating its surface temperature is in the second range of the G class. The solar constant is the amount of power that the Sun deposits per unit area that is directly exposed to sunlight.
data. Beta Canum Venaticorum ( β Canum Venaticorum, abbreviated Beta CVn, β CVn ), also named Chara / ˈkɛərə /, [12] [13] is a G-type main-sequence star in the northern constellation of Canes Venatici. At an apparent visual magnitude of 4.25, it is the second-brightest star in the constellation. Based upon an annual parallax shift of 118 ...
The principal component of the Solar System is the Sun, a G-type main-sequence star star that contains 99.86% of the system's known mass and dominates it gravitationally. The Sun's four largest orbiting bodies, the giant planets, account for 99% of the remaining mass, with Jupiter and Saturn together comprising more than 90%.
