### When was The Star Fraction created?

The Star Fraction was created in 1995.

### How small is the normal star?

Our Sun is above average; the average star is a red dwarf, with a fraction of the mass of our Sun, and a fraction of its diameter.

### How massive does a star need to be (at least) in order to form a black hole when it collapses?

Current estimates suggest that a star must be at least 25 times the mass of the sun to form a black hole. In most cases only a fraction of the star's mass will actually go in to forming the black hole.

### What causes pulsating variable stars to pulsate?

When the core of a massive star is compressed during a supernova explosion, then collapses into a neutron star, it retains most of its angular momentum.Since it has only a tiny fraction of its original radius, a neutron star is formed with a very high rotational speed.A pulsar is a highly magnetised, dense neutron star emitting a beam of electromagnetic radiation.

### How is a unit fraction alike from a fraction?

### How a human being would fare on stars?

A human being placed on or near a star would have no problem whatsoever and nothing to worry about, as he would be vaporized in a fraction of a second.

### How many earths would go into a neutron star?

If you mean in the same volume, only a tiny fraction of Earth - the neutron star is much smaller. The radius of a typical neutron star is perhaps 12 kilometers. In comparison, the Earth has a radius of about 6371 kilometers - that makes Earth's volume about 150 million times greater. (On the other hand, the neutron star has a much greater mass than Earth.)

### Why is it rare for a star to become a black hole when it dies?

It is rare for a star to become a black hole when it dies because the conditions needed for a star to collapse into a black hole require very specific properties, such as a large mass and density. Most stars, especially lower-mass stars like our Sun, do not have enough mass to undergo this process and instead end their lives as white dwarfs or neutron stars.

### What is the formula for calculating the area of a star shape?

Star shapes vary greatly. It's probably best to divide the shape into triangles (or other figures you can find the area of) and deal with those. For symmetric five-pointed stars, the area of a star can be approximated within .024% by taking the distance between two consecutive points, squaring it, and multiplying it by the fraction 13/16.

### Different kinds of fraction?

different kinds of fraction: *proper fraction *improper fraction *mixed fraction *equal/equivalent fraction

### What can 87.5 be divided into a whole fraction?

There cannot be a whole fraction. If it is a fraction it is not whole and if it is whole it is not a fraction.
