What is a 1 solar mass star?
Stage 1- Stars are born in a region of high density Nebula, and condenses into a huge globule of gas and dust and contracts under its own gravity. Stage 5 – A star of one solar mass remains in main sequence for about 10 billion years, until all of the hydrogen has fused to form helium.
How many Earth masses does the sun have?
333,000
Mass and volume About 1.3 million Earths could fit inside the sun. The mass of the sun is 1.989 x 1030 kilograms, about 333,000 times the mass of the Earth.
How many solar masses is an average star?
There is no absolute agreement on what is an average star, but we’ll define it like this: An average star, or more properly, an intermediate-mass star, ranges from approximately 0.5 to 8 solar masses during the beginning of its life.
How much is the sun shrinking?
Every 11 years, the sun’s radius oscillates by up to two kilometres, shrinking when its magnetic activity is high and expanding again as the activity decreases. We already know that the sun is not a static object. Its surface is regularly covered with darker areas known as sun spots and brighter areas known as flares.
What is the weight of sun?
1.989 × 10^30 kg
Sun/Mass
What is the exact mass of sun?
Bulk parameters
Sun | Ratio (Sun/Earth) | |
---|---|---|
Mass (1024 kg) | 1,988,500. | 333,000. |
GM (x 106 km3/s2) | 132,712. | 333,000. |
Volume (1012 km3) | 1,412,000. | 1,304,000. |
Volumetric mean radius (km) | 695,700. | 109.2 |
Are there planets bigger than the sun?
Explanation: To begin with planets, as that is the easiest question to answer, there are no planets bigger than the Sun or even close to the size of the Sun. At about 13 times the mass of Jupiter a planet becomes what is referred to as a “brown dwarf”.
How long will a star of 16 solar masses live?
Classification of stars
Class | Mass (in solar masses M☉) | Lifespan of the star (years) |
---|---|---|
O | > 16 M☉ | 11 million |
B | 2.1 – 16 M☉ | 11 million – 1 billion |
A | 1.4 – 2.1 M☉ | 1 billion – 2.2 billion |
F | 1.04 – 1.4 M☉ | 2.2 billion – 10 billion |
Can the Sun burn out?
For about a billion years, the sun will burn as a red giant. Then, the hydrogen in that outer core will deplete, leaving an abundance of helium. Astronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies.
