What else can I help you with?
How many light minutes is an AU?
1 AU (astronomical unit) is approximately equal to 8.3 light minutes. This is the average distance from the Earth to the Sun.
What are au's?
An au is an astronomical unit, or how far light will travel in a year.
Is it true a light year is a unit of time?
Yes, indeed it is. An astronomical unit is 8.3 light minutes. So light years are indeed a unit of time used in space, but not in our solar system, because our solar system is not big enough to use light hours. An astronomical unit, by the way, is the distance from the sun to Earth.
Is a astronomical unit larger than a light year?
An astronomical unit is not larger than a light year. A light years is considered to be approximately 62,000 times larger than an astronomical unit.
What is the unit of measurement you use in your solar system?
the units used are light seconds, minutes, hours and astronomical units.
Is a light year have greater distance or a astronomical unit?
A light year is about 63,000 times greater than an astronomical unit.
Which is longer a light year or an astronomical unit?
A light year is much bigger, an AU is only about 8 light minutes.1 light year = 63,240 AU
What unit is larger than a kilometer but smaller than a light year?
See the Question "http://wiki.answers.com/An_astronmoical_unit_is_a_larger_distance_unit_than_a_light_yearQuote "One light year is about 63,200 AU. An astronomical unit is about 8 light-minutes."
What is the order of increasing length of astronomical unit parsec kilometer and light year?
kilometer, AU (astronomical unit), light year, parsec.
Is an astronomical unit larger than a light year?
No, an astronomical unit (AU) is the average distance between Earth and the Sun, approximately 93 million miles. In comparison, a light year is the distance that light travels in one year, which is about 5.88 trillion miles. Therefore, a light year is significantly larger than an astronomical unit.
How long does it take to travel one astronomical unit?
That cannot be answered unless the velocity is known.
How would you use an atronomical unit?
The astronomical unit is the mean distance from Earth to Sun. It is commonly used for distances in the Solar System. This way, it is easier to imagine the distances, since the meter or kilometer are very small units (an astronomical unit is about 150 million km, or 150 billion meters), and the light year and the parsec are very large units (a light-year is about 63,000 astronomical units, the parsec is even larger). Light-minutes or light-hours might be used instead, within the Solar System, but the astronomical unit has become quite popular.
