If a star's parallax angle is too small to meaure what can you conclude about the star distance form earth?
It means that its distance is farther than can be detected. For example, if the smallest angle that can be detected is 1/100 of an arc-second, it would mean that the star is farther than about 100 parsec.
Even though this star has an absolute magnitude greater than that of sirius it looks dimmer from earth since its 100 times farther away?
Rigel has a greater absolute magnitude than Sirius but apears dimmer from Earth do to the farther distance the light waves must travel through space (just a little more information : ), but there are probably alot more stars around that distance
Is the Earth a plant or a star?
Earth is a planet. A star would be much more immense and powerful; for example, the sun.
List three factors that control the apparent brightness of a star as seen from earth?
Three factors that affect a star's brightness are the star's distance from earth, its age and its luminosity. The farther the star is from earth, the less bright it appears. As a star increases in age, its brightness also increases. Its brightness also depends on its luminosity, which is the amount of energy the star emits per second.
What would the result be if the distance of the earth to the sun were more than 149million km?
If the Earth were farther from the Sun, then it would be colder on Earth. Also, the years would be longer.
Which is true The more a star appears to move the farther it is from earth The less a star appears to move the farther it is from earth Stars that do not appear to move are very close to earth?
The less a star appears to move the farther it is from earth is true.
The farther a star is away from earth the more it is?
red shifted
Is moon is farther or star is farther from earth?
Some stars are very far, more then Saturn so they look small.
Is one star is between the earth and the moon?
No. The moon is the closest astronomical object to Earth. The closest star to Earth is the sun, which is about 400 times farther away than the moon. The next nearest star is more than 260,000 times farther away than the sun.
Is the sun a giant star farthest from Earth?
No. The sun is the nearest star to Earth. The next closes star is more than 250,000 times farther away. The sun is larger than the average star, but not a giant.
Why would a star that is farther than earth be brighter than a star closer to earth?
same as:Why_would_a_star_that_is_farther_away_from_earth_be_brighter_than_a_star_that_is_closer_to_earth
Is the sun closer to earth than a star?
The sun is a star, the closest one to Earth. The next nearest star to Earth is about 265,000 times farther away than the sun is.
What is more farther star or moon?
lol the moon
Is Uranus farther away from earth than the star Rigel?
No. Rigel is much farther away than Uranus. Uranus is in our Solar System.
What star looks dimmest from earth?
What star even tho this star has an absolute magnitude greater than that of Sirius it looks dimmer from earth since it's 100 times farther away

Is pole star further than earth or sun?
Yes, Polaris, the proper name for the pole star, is much farther away than the distance between the Earth and the Sun.
