How big is a star compared to the earth?
Stars are significantly larger than Earth. For example, the Sun's diameter is about 109 times that of Earth. Larger stars, such as Betelgeuse, can be hundreds or even thousands of times larger than the Sun.
When viewed from earth a red star and a blue star appear to be equally bright what could you infer about these two stars?
If a red star and a blue star appear to be equally bright from Earth, it suggests that they have similar apparent magnitudes. However, since blue stars are typically hotter and more luminous than red stars, the red star may be much closer to Earth than the blue star, compensating for the difference in intrinsic brightness. This scenario indicates that the two stars have different temperatures, sizes, and possibly different stages in their stellar evolution.
Is a star bigger than a nova?
Some stars are
Which star is larger neutron star or subgiant star?
A subgiant star is larger than a neutron star. Neutron stars are incredibly dense and compact remnants of massive stars, while subgiant stars are in a transitional phase between main sequence and red giant stages, typically larger and more diffuse than neutron stars.
Can a yellow star be bigger than a blue?
Yes, the color of a star is determined by its temperature, with blue stars being hotter than yellow stars. The size of a star is determined by its mass, age, and stage of life, so a yellow star can potentially be bigger than a blue star depending on these factors.
What are the main differences between stars and the sun?
The sun is a star. Its different to us than other stars because it is the closest to our planet.
Are all bright stars the same temperature?
No, bright stars can have different temperatures. The color of a star typically indicates its temperature, with blue stars being hotter than red stars. Brightness is influenced by both temperature and size; a larger, cooler star could appear brighter than a hotter, smaller star.
Suppose you see two stars a blue star and a red star what can you conclude about the two stars?
The color of a star is influenced by its temperature, with blue stars being hotter than red stars. Therefore, you could conclude that the blue star is hotter than the red star. Additionally, blue stars typically have shorter lifespans than red stars.
How is a star compared to the earth?
It depends on what star you compare it to. Stars have many different sizes. Our sun is a star and it is approximately a million times larger than the earth.
What is an orange star?
An orange star is a type of star that appears orange in color due to its temperature and spectral characteristics. These stars are cooler than white or blue stars, with temperatures typically ranging from 3,500 to 5,000 Kelvin. Orange stars are common in the universe and can be found at different stages of their stellar evolution.

What is bigger a planet or a star?
Stars are much bigger than planets. The only stars that are smaller than planets are neutron stars.
How does the red star and the blue star compare to the sun?
Our Sun is basically yellow. Our Sun's surface temperature is higher than that of a red star, and lower than that of a blue star.Other than that, it's hard to make comparisons, since both red stars and blue stars come in VERY different sizes.
What is in a star?
A star is made of hot gases. When they start out, they are almost entirely Hydrogen. During the main sequence, they fuse the hydrogen into helium which is heavier. They also produce smaller amounts of heavier elements like Carbon, Oxygen, Iron, Silicon and Neon. Some stars may contain other elements and earlier Population III and II stars are a bit different. They had less metals than more recent Population I stars like the sun.
How do star are more brighter than other stars?
Stars are more brighter than other stars because they have different characteristics that affect their luminosity. Luminosity is the amount of energy that a star emits per unit of time. It depends on the star's size, temperature, and distance from the observer. Some of the factors that make stars more brighter than other stars are: Size: Larger stars have more surface area and can emit more light than smaller stars. Temperature: Hotter stars have higher energy and can emit more light than cooler stars. Distance: Closer stars appear brighter than farther stars because their light has less space to travel and lose intensity.
Is a star bigger than a planet?
Yes, a star is generally much larger than a planet. Stars are massive celestial bodies that generate light and heat through nuclear fusion, whereas planets are smaller bodies that orbit stars.
