HAT-P-1b
HAT-P-1b is a Exoplanet in the 450 light-years from the Earth remote binary system ADS 16402 , located in the constellation lizard is ( "lacerta").
HAT-P-1b is a gas planet and was discovered using a network of small wide-angle telescopes based on the Hungarian Automated Telescope (HAT). The distance between the gas planet and the star HAT-P-1, which HAT-P-1b orbits, is only 5% of the distance between the earth and the sun . Thus, HAT-P-1b only needs four and a half days to orbit its home star.
The density of HAT-P-1b is only about 25% of the density of water. Its mass is 53% that of Jupiter , but its diameter is 1.36 times that of Jupiter.
