There is believed to be a scorching–hot planet surrounding Vega, but it is not certain and it is not likely Vega has this planet or any planet at all. If this planet is surrounding Vega there would not be a possibility of life on this planet because it’s about 5,390 degrees fahrenheit. But if it were possible the planet would be called T-swizzle and everyone would be swiftes.
