When a star collapses to half size what does the gravitational field at its surface do?
The gravity at its surface increases.
You can measuring the altitude of a star by measuring the angle between your horizon and the star using a?
We would typically use a sextant to measure the angle of a star above the horizon.
How did they now Goldilocks is a planet?
A "Goldilocks planet" is ANY planet that orbits its star at a distance from that star where the heat from the star means that any water present on the planet is in liquid form. This can be determined by measuring the stars temperature (its size and colour) and observing the planets orbital distance.
How do you know the sun is a typical star?
Through measuring how much luminosity it is giving out, measuring the size of the star, and find out how hot the star is, we can categorize each star in a graph. Our sun just happens to be part of the main sequence of stars; the sun is not as big as a giant or a super giant star nor is it as small as a white dwarf so therefore the sun is in between. Main sequence stars are more common because they are very stable so it wont change over a long course of time, unlike variable stars, which changes its size and luminosity. A variable star has a period of a day to a month. A period is how long it takes for the star to return to its starting point as it changes in a cycle.

How does brigthness vary from the size of the star?
this depends of the distance away from us and the size of the star
Who was the star of TV show gidget?
Sally Field was the star of the TV show "Gidget."
How can the color of starlight reveal the temperature of a star?
The colour of starlight reveals the temperature of a star by wavelengths in the electromagnetic spectrum, to give a measuring tool for star temperature.
How does gravity cause a star to wobble?
the star's size
What factor affects the luminosity of a star?
the size of a star
How is the sun different in size and temperature from a star?
It isn't. The sun is a star and there are others that are similar in size and temperature.
