Scientists determine the mass of the Sun using the gravitational effects it has on nearby celestial bodies, particularly the planets. By observing the orbits of planets, such as Earth, and applying Kepler's laws of planetary motion along with Newton's law of universal gravitation, they can calculate the Sun's mass. The relationship between a planet's orbital period and its distance from the Sun allows for precise measurements, leading to an estimated mass of about 1.989 x 10^30 kilograms.

How do you determine the Milky Way's mass outside the Sun's orbit?
Scientists determine the Milky Way's mass outside the Sun's orbit by observing the motions of stars and gas in the galaxy and using gravitational models to calculate the total mass that is needed to hold these objects in their orbits. This method allows for estimating the mass of the Milky Way's dark matter halo, which makes up the majority of its mass.
How do you know what goes on under the surface of the Sun?
Astronomers create mathematical models that use the laws of physics, the Sun's observed composition and mass, and computers to predict internal conditions. By measuring Doppler shifts, we observe vibrations of the Sun's surface that are created deep within the Sun.
How can astronomer's determine the mass of the Sun?
Astronomers can determine the mass of the Sun by studying the orbits of planets and other celestial bodies in our solar system. By applying Newton's laws of motion and gravitation, they can calculate the Sun's mass based on the gravitational forces that shape these orbits. Additionally, observations of the Sun's effects on nearby stars can also provide valuable data for estimating its mass.
How do scientists know what the sun is made of?
Scientists know what the sun is made of by studying its spectrum. By analyzing the light emitted by the sun, they can identify the different elements present in its atmosphere based on the unique patterns of absorption and emission lines. This approach allows scientists to determine that the sun is mainly composed of hydrogen and helium, with trace amounts of other elements.
Determine the mass of the Sun using the known value for the period of the Earth and its distance from the Sun?
The mass of the Sun can be determined using Kepler's Third Law of Planetary Motion, which relates the period of a planet's orbit to its distance from the Sun. By knowing the period of Earth's orbit (1 year) and its average distance from the Sun (1 astronomical unit), we can calculate the Sun's mass to be approximately 1.989 x 10^30 kg.
How to calculate the mass of the sun?
To calculate the mass of the sun, scientists use the gravitational pull it exerts on other objects, like planets. By observing the orbits of planets around the sun and applying Newton's law of universal gravitation, they can determine the sun's mass. This method is based on the relationship between the mass of an object and the gravitational force it generates.
What is the method used to calculate the mass of the sun?
The method used to calculate the mass of the sun is by observing the orbits of planets and other celestial bodies around it, and applying Newton's law of universal gravitation to determine the gravitational force exerted by the sun. This information, along with the distance of the objects from the sun, allows scientists to calculate the mass of the sun.

How can we determine the amount of mass in our galaxy?
Scientists determine the amount of mass in our galaxy by studying the movements of stars and other celestial objects. By observing how these objects move and interact with each other, scientists can calculate the total mass of the galaxy. This helps us understand the structure and dynamics of our galaxy.
How are stars made of?
Our Sun is about 70% Hydrogen and 28% Helium by mass, with traces of heavier elements. Other stars can be a little different, but with a spectrometer, scientists are able to determine the elements that are present in any star.

How do scientists determine the atomic mass of an atom?
Scientists determine the atomic mass of an atom by averaging the masses of all the isotopes of that element, weighted by their abundances. This information can be obtained from mass spectrometry data and is used to calculate the weighted average mass. The atomic mass is typically reported in atomic mass units (amu).
How do astronauts determine the temperature of the sun?
Scientists and astronauts have determined that the sun is over 10 thousand degrees. They came to this conclusion by measuring the light and gases the sun gives off and determining the temperature.
