Did rick harrison from pawn stars die?
As of 2014, he is alive, and turns 31 in April (apparent birthdate April 27, 1983).
Why do stars appear to move across the sky each night while the pattern of stars stays the same?
Every star in the sky has "proper motion", meaning its own motion in some direction, besides the apparent daily motion that's due to the rotation of earth.Why don't we see any effects of this motion ? The answer is very simple, but still mind-boggling.We don't see the effects of a star's proper motion during many human lifetimes because the stars are so far away. Any more than you could see a snail running for all he's worth across the road, 100 miles away.Here are a few examples of the distances involved in space, coupled with the limitations of human perception:-- The nearest natural body to the earth is the moon. Its distance from earth is about [1/4 of a percent] of the distance to the sun ! On an astronomical scale, we can practically reach out and grab the moon. Now, the moon is moving more than 2,000 miles per hour in its orbit. But we can look right at it and never notice that motion ... even though it's the nearest body in the universe to earth.-- Now consider the nearest star to earth (aside from the sun). It's 4.4 light-years away from us ... more than 100 MILLION times as far from us as the moon is, and that's the NEAREST star to us.If that star moved across our line of sight at the SPEED OF LIGHT, it would take 14 days to move the apparent size of the full moon.If it moved across our line of sight at a speed of 1 million miles per hour, it would take almost 26 years to move the apparent size of the full moon.And that's the NEAREST star to us !That's why we don't notice the proper motion of the stars. If anybody is left in several thousand years from now, and if they have our records of how the sky used to look in the 21st Century, then they'll see the results of the motion of the stars. But we see essentially the same sky as the earliest humans who left us any records.
Why do you think there are so few dwarf stars among the twenty with the highest apparent brightness?
Probably because they are the closet to us!
What the relationship between magnitude and size of the star?
The brightness of a star depends on its temperature, size and distance from the earth. The measure of a star's brightness is called its magnitude. Bright stars are first magnitude stars. Second magnitude stars are dimmer. The larger the magnitude number, the dimmer is the star.The magnitude of stars may be apparent or absolute.
What are the release dates for The Daily Orbit - 2012 Cloudy Brown Dwarf Stars 2-83?

What causes the apparant movement of stars in the sky?
The real motion of stars is hardly noticeable even over a period of many years. It's the Earth's daily rotation the is the main cause of their apparent motion. (Stars are so far away that the Earth's revolution around the Sun hardly cases any apparent motion.)
What is a stars apparent shift in position?
Motion
Why do stars appear to move in the sky?
Stars appear to move in the sky due to the rotation of Earth on its axis. As Earth spins, it causes the stars to appear as if they are moving across the sky. This is known as the apparent motion of the stars.
Compare the apparent motion of star to the actual motion of stars?
The actual motion of stars is very hard to see because stars are very far away.
When does a planet is said to be in retrograde motion?
A planet is said to be in retrograde motion when its apparent motion - the motion as seen by us, against the background stars - is from east to west.Planets spend more time in prograde motion, from west to east. The apparent movement of Sun and Moon against the background stars is also from west to east. Not to be confused with the daily motion, due to Earth's rotation.
Do stars appear to move due to the earths rotation?
Yes, stars appear to move across the sky due to the Earth's rotation on its axis. As the Earth spins from west to east, stars seem to rise in the east and set in the west, creating a daily arc. This apparent motion is most noticeable at night when the sky is clear, making it easy to observe the changing positions of stars over time.
What happens during the apparent retrogate motion of a planet?
When that happens, the planet moves from east to west, from our point of view. This should not be confused with the daily motion of all stars + planets due to Earth's rotation; rather, to the planet's movement against the background of the stars.
The apparent motion of stars is due to movement of?
The rotation of the Earth makes the stars appear to move in the sky.
Why there are seasons and the apparent motion of the stars and sun?
Seasons are caused by the tilt of Earth's axis as it orbits the Sun, which creates variations in temperature and daylight. The apparent motion of the stars and the Sun is due to Earth's rotation on its axis, giving the illusion that these objects move across the sky.
In what direction is the sun's annual motion relative to the fixed stars?
The Sun's annual motion is from west to east relative to the fixed stars due to the Earth's orbit around the Sun. This apparent motion is caused by the Earth's revolution around the Sun, giving the illusion that the Sun is moving against the background of stars in the sky.
Do circumpolar stars move counterclockwise around the north celestial pole?
Yes, circumpolar stars appear to move counterclockwise around the north celestial pole due to the rotation of the Earth on its axis. This motion is known as diurnal motion and is responsible for the apparent daily movement of stars in the night sky.
How does a geocentric model explain the apparent motion of the stars?
All the stars are fixed to a sphere, which rotates once in 24 hours.
