What two characteristics are stars classified by?
They are classified by the amount of Light they give off, and their temperature.
Why the stars are twinkling?
Stars twinkle because of the Earth's atmosphere. As the light from a star passes through the various layers of the atmosphere, it gets refracted or bent, causing the star's brightness to fluctuate slightly. This bending of light is what creates the twinkling effect that we see from Earth.
How does a stars temperature affect its appearance?
Basically the more intense the heat the star is giving off the brighter the star will appear to be. For example, let's say there is a red colored star and a white colored star in the vicinity of the planet you're currently on to observe them. The red colored star is giving off light at the visible spectrum that reveals red most prominently. I'm not 100% sure how the colors line up but I do know that red is a lower frequency wavelength of light then pure white. This means that the higher the temperature of the star the brighter light it will give off, by bright of course I mean the higher frequency colors slowly approaching pure white light.
What is the name for the change in a stars spectrum when it moves away from the earth?
The change in a star's spectrum when it moves away from the Earth is called redshift. This shift occurs because the wavelengths of light emitted by the star are stretched out as the star moves away, causing the light to appear more red.
The center of every solar system is?
A star, or stars.
Is the moon the star of earth?
No, the moon is not a star. It is Earth's natural satellite, meaning it orbits around the Earth rather than being a luminous celestial body like a star. Stars are massive, luminous spheres of plasma that emit light and heat, while the moon reflects light from the sun.
How can you tell Jupiter is not a star?
Jupiter is a planet, not a star, because it does not generate its own light through nuclear fusion like stars do. Instead, Jupiter reflects light from the Sun. Additionally, Jupiter is much smaller than stars and orbits a star (the Sun) like other planets in our solar system.
Does the moon reflect light from the stars?
The moon reflects light from one star in particular: the sun.
How are the sun and moon different?
The sun is a star that is extremely hot and is a source of light for the planet. While the moon is a mass that orbits around earth and reflects light.
To calculate the mass of a star scientists study?
the orbits of binary stars
What is the relationship between the stars the sun and the moon?
Stars, including the sun, are luminous celestial bodies that emit their own light, while the moon is a non-luminous body that reflects light from the sun. The sun is a star that is much closer to Earth than other stars, and the moon orbits Earth, influencing tides and providing illumination at night.
Why doesn't the moon not make light?
The moon is not a star. The moon only reflects the suns light. Only stars make light. Our sun is a star.
What are the stars that the earth orbits around?
The Earth orbits one star, which we simply call "Sun".
Is star a light source?
no..it reflects light
Why is Venus a planet not a star?
Stars are mainly made of hydrogen and helium, and produce energy and light with atomic fusion at the core. Venus is made of rock and doesn't produce light, it just reflects light from the sun. Also, stars are hundreds of times bigger than Venus.
Are the sun and moon both stars?
No, the sun and the moon are not both stars. Our Sun is known as a Main Sequence star, or just an average sized star. Our moon is a planetary satellite, but are kept as moons for short. A star is classified if it is bright and burns hydrogen and helium gas, while a moon, or planetary satellite, are classified when a smaller rocky object (the moon) orbits a planet.
How is the moon and the sun not alike?
The Sun is a star and emits solar light, and is at the centre of our Universe. The Moon is a small satellite planet that orbits the Earth, and only reflects the light striking the Moon's surface.
