Palpitations can also be a sign of serious heart trouble. Palpitations that are caused by certain types of abnormal heart rhythms (arrhythmias) can be serious, and even fatal if left untreated. Recognizable arrhythmias are present in a small number of patients who have palpitations.
The sun has a diameter of 865,000 miles or 1.39 million kilometers. Its diameter is 109 times the diameter of earth. Despite its seemingly huge size in comparison to earth, the sun is actually considered a small star and is classified as a yellow dwarf. The sun is mainly composed of hydrogen and helium.n about eight billion years it is estimated that the sun's radius (and consequently its diameter) will increase greatly due to the large amount of heat that the sun produces. This increase in heat will also change the sun's intensity by 10%, and will most likely have a very disastrous impact on Earth.
That depends on how you reckon size. The Sun is 109 times as wide as the Earth. Also, the Sun has 12,000 times the surface area of the Earth, 1.3 million times the volume, and 333,000 times the mass. Our Sun is not too shabby as stars go, but there are many out there much bigger.
