How do the mass and density of the sun compare to those of Earth?
The radius of the sun at 696,000 km is 109 times the Earth’s radius. Its surface gravity is 274 m/s2 or 28.0 times that of the Earth. Its mean density is 1410 kg/m3 or 0.255 times the mean density of Earth….Sun.
| Mass (Earth=1) | 332,800 |
|---|---|
| Mean distance to Earth, 106 km | 149 |
| Density (water=1) | 1.41 |
| Surface gravity m/s2 | 274 |
What is the correct order of objects in the solar system from smallest to largest?
From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid.
What is the approximate percentage difference between the aphelion and the perihelion distances relative to Earth’s average distance from the sun?
On average, Earth is about three million miles—or about 3 percent—farther from the sun at aphelion than at perihelion.
What are the three layers of the sun’s atmosphere in order of increasing distance from the surface?
In order of increasing distance from the center of the Sun, they are the photosphere, with a temperature that ranges from 4500 K to about 6800 K; the chromosphere, with a typical temperature of 104 K; the transition region, a zone that may be only a few kilometers thick, where the temperature increases rapidly from 104 …

What order is the solar system?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine.
What is the difference between perihelion and aphelion?
Every planet has points in the orbits when they are farthest or closest away from their star. For example, planet Mars has an even more elliptical orbit than Earth. In comparison, Earth’s orbit seems almost circular; this almost-circular orbit may be why Earth’s climate is relatively stable.
How do you find the average of aphelion and perihelion?
The perihelion distance P=a(1−e) and the aphelion distance A=a(1+e) where e=0.875 is the eccentricity. This gives a perihelion distance of 2.375AU and an aphelion distance of 35.625AU.
What are the 3 layers of the sun’s atmosphere?
The sun’s atmosphere is made up of several layers, mainly the photosphere, the chromosphere and the corona.
What are the 7 layers of the sun in order?
It is composed of seven layers: three inner layers and four outer layers. The inner layers are the core, the radiative zone and the convection zone, while the outer layers are the photosphere, the chromosphere, the transition region and the corona.
How do you find the density of an atom with mass?
First, we have the number density, which is n = number of atoms volume. Then we also have the mass per atom, μ = mass atom. It is easy to see by combining these equations that the density is then ρ = n μ – it depends on both number density and atomic weights.
What is the average density of an atom on a macroscopic scale?
There is relatively little empty space between atoms in solids and liquids, so that the average density of an atom is about the same as matter on a macroscopic scale—approximately 10^3 kg/m^3 . The nucleus of an atom has a radius about 10^-5 that of the atom and contains nearly all the mass of the entire atom.
Does density depend on a or R?
This means that the density does not depend on A or on r – it is related to constant values – it is therefore a constant value and uniform. The most definitive information about nuclear sizes comes from electron scattering experiments.
How do you find the atomic mass of a neutron?
= neutron mass, m(Z,N) = mass of nucleus with Z,N • B>0 • With B the mass of the nucleus is determined. • B is very roughly ~A m(Z,N) Zm Nm B/c2 = p +n− Most tables give atomic mass excess ∆ in MeV:
