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.
It was discovered by William Herschel in 1781. It has an equatorial diameter of 51,800 â¦ kilometers (32,190 miles) and orbits the Sun once every 84.01 Earth years. It has a mean distance from the Sun of 2.87 billion kilometers (1.78 billion miles). It rotates about its axis once every 17 hours 14 minutes.
