While such methods have been performed on the planet after its discovery, they have not yet detected what the orbital eccentricity of the planet actually is, and have as of March 2012 only set an upper limit on the mass of the planet. Physical characteristics .Kepler-22b's radius is roughly 2.4 times the radius of Earth. Its mass and surface composition remain unknown, with only some very rough estimates established: it has less than 124 Earth masses at the 3-sigma confidence limit, and less than 36 Earth masses at 1-sigma confidence. The Habitable Exoplanets Catalog gives a mass estimate of 6.36 Earth masses (and a radius of just 2.10 Earth radii) for the planet as of October 2012, after initially estimating it at ~10-35 Earth masses. Kepler-22b might be an "ocean-like" world.
These five toxic, non-metallic elements make up Group 17 of the periodic table.Fluorine and chlorine are gases. Bromine is one of only two liquid elements. Iodine is a solid. Astatine is radioactive and is one of the rarest of the chemical elements. Alkaline Earth Metals IS made up of six elements.
He built his own telescopes and was the first to use to view the heavens in 1610. After doing so, he made many discoveries. He saw that Jupiter has moon orbiting around it, like the Earth. He made the discoveries of the four moons on January 7, 1610 and they are now called the Galilean moons. These are the largest of Jupiters moons.
Some students believe that the Earth’s tilt changes in degree as the seasons change and that the axis points in different directions as the Earth orbits the Sun. In reality the Earth’s axis is always tilted at 23.5 degrees and the North Pole always points toward Polaris (Lambert, 2010). Most of the planets in the solar system have nearly circular orbits, much like Earth. The orbits do, however, have an elongated shape. The orbits of Mercury and Pluto are very elongated whereas the orbits of the other planets are almost circular (Nelson, 2005).
Observation 5, the moon was waxing gibbous, in southwest direction. Observation 6, the moon was in east direction, waxing gibbous phase. Observation 11, the moon was in southwest direction and it was in waxing gibbous phase. Observation 16, the moon was full moon and it was in southeast direction After carefully noticing its position compared to some nearby stars, I can see that in one hour, the moon’s position relatively to the stars changed by one moon – diameter. 2/ The moon rises and sets later than the last time I observed.
3 laws of planetary motion- a Danish astronomer whose observations of the planets provided the basis for Kepler's laws of planetary motion. Galileo- He proposed a model of the solar system in which the planets orbit in perfect circles around the sun; his work ultimately led to rejection of the established geocentric cosmology. Laws of motion- was a German mathematician, astronomer and astrologer, and key figure in the 17th century scientific revolution.
