How big is a sunspot?
Sunspots expand and contract as they move across the surface of the Sun and can be as large as 80,000 kilometers (50,000 mile) in diameter, making the larger ones visible from Earth without the aid of a telescope
Does Neptune have any sunspots on it?
No, sunspots are on the sun. Neptune does have a big dark spot, but it's not a sunspot.
What is the largest sunspot?
Prominence Sunspot in 1945
What are sunspot maximums and sunspot minimums?
Sunspot maximum and sunspot minimum are the points in time (roughly 6 years apart) when the sun is producing the most, or the least sunspots. In the past this has been measured both by sunspot area and sunspot count and is directly tied to the solar magnetic cycle.
How often is the sunspot cycle?
About 11 years on average - but there are large variations in the length of individual cycles. Once each sunspot cycle, the magnetic field on the Sun reverts - so the real (underlying) cycle is about 22 years. (It takes two sunspot cycles for the magnetic field to go back to the original position.)
What is an example of a sunspot?
This question makes no sense. It's like asking "what is an example of a pencil?" A pencil is a pencil, and a sunspot is a sunspot.
How many years is the sunspot cycle?
The sunspot cycle is about 11 years in length.
Why do sunspots look small but are big?
Sunspots only look small in relationship to the size of the Sun itself. Even a "small" sunspot, hardly visible, is as big around as the Earth is.
Do meteors cause sunspot?
No they do not. S sunspot is basically a magnetic storm on the the Sun's Photosphere.
Are sunspots the same size?
No. Some sunspots are fairly small, compared to the size of the Sun, while some can get pretty big. Sunspots grow, and merge, and a "medium" sized sunspot covers an area larger than the Earth. You can see the daily sunspot number on the web at www.spaceweather.com.
What is a cooler area on the sun's surface?
An area on the sun that is cooler is called a sunspot.
What is the significance of sunspot regions the sun?
A sunspot is a part of the Sun that is cooler, and therefore darker, than the surroundings.
