Look at the figure below. How many stars are within light-years () of the Sun? Would that number be about the same or much different if Earth orbited another star in this figure? (The field of view is wide in the figure.)
A. There are no stars within of the Sun. The number would be much differen
B.
| . Stars within of the Sun are confined to about two stars. The number would be about the same. |
C. Stars within of the Sun are confined to about stars. The number would be about the same.
D.. Stars within of the Sun are confined to about
eight stars. The number would be much different.

How long does it take light to travel from the Sun to the Earth? The Sun’s nearest neighbor among the stars, a dim little star called Proxima Centauri, is at a distance of 1.295 parsecs from us. How long does it take light to travel from Proxima Centauri to the Earth?

Proxima Centauri, the nearest start to the Sun, is about 4 light years from Earth, and Antares is about 520 light years from Earth. Antares is a very bright star easily seen with the naked eye but Proxima Centauri is so dim that a small telescope is needed to see it. What can you say about the relative luminosities of Antares and Proxima Centauri?

f) in vacuum, light travels at about 186,282 miles per second. One mile is about 161 kilometers (km). Astronomers prefer to use units of distance that are reasonable in describing how far objects are from Earth. For example, for distances in the solar system we use the astronomical unit (AU), which is equal to the average distance of Earth from the Sun; 1 AU is about 150 million km. For distances to stars and galaxies, astronomers use the light-year (1...

Neutron stars, such as the one at the center of the Crab Nebula, have about the same mass as our sun but a much smaller diameter. Part A If you weigh 665 N on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 16.0 km ? Take the mass of the sun to be ms = 1.99×1030 kg , the gravitational constant to...

choose correct answer. no explanation needed
QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...

The Apparent Motion of the Surn The sun rises in the east, moves across the south, and sets in the west much as stars in non-circumpolar constellations do. Just as for the stars, this apparent motion is really due to the rotation of the earth on its axis The Earth's motion around the Sun adds a complication to the Sun's apparent motion. In a full year, or 365 days, the Earth would go completely around the Sun so that the...
