s there for this ? The universe consists of billions of galaxies that each contain billions of stars. Around some stars Planets and moons trace elliptical orbits. Within these orbits there are spherical bodies. These range in size from large asteroids to tiny particles smaller than a grain of dust‚ all of this is classified as baryonic matter by Astronomers. The fundamental core of the universe is known as the atom. During the 1970’s astronomers collected information surrounding the mass of

SES4U Final Assessment Part 1: Impact Craters An impact crater (impact basin or sometimes crater) is a circular depression on a surface‚ usually referring to a planet‚ moon‚ asteroid‚ or other celestial body‚ caused by a collision of a smaller body (meteorite) with the surface. In the center of craters on Earth a crater lake often accumulates‚ and a central island or peak (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake. Ancient craters whose relief

overestimation of Neptune’s mass.[3] After 1992‚ the discovery of numerous small icy objects with similar or even wider orbits than Pluto led to a debate over whether Pluto should remain a planet‚ or whether it and its neighbours should‚ like the asteroids‚ be given their own separate classification. Although a number of the larger members of this group were initially described as planets‚ in 2006 the International Astronomical Union reclassified Pluto and its largest neighbours as dwarf planets‚ leaving

Most scientists think that our solar system was made from a nearby star‚ called the supernova. These scientists believe that the explosion of the supernova squeezed a nearby cloud of dust‚ causing it to collapse. When the gravity gathered the dust together‚ it formed something called a solar nebula. Soon‚ the cloud became hotter‚ a disk of gas surrounding it. Molecules gathered in a clump as the disk got smaller. Scientists believe in this theory using technology. They used this technology to observe

Can you answer that? Well‚ a planet is described as a celestial body that is in an orbit of the Sun‚ has a near round shape‚ and doesn’t enter an asteroid field. Simple answer‚ right? No‚ Mostly because when Pluto was a planet‚ it had most of all of those features‚ only that it didn’t orbit the sun like the closer planets. Pluto was considered a dwarf planet after only fulfilling 2 requirement‚ no Planeteering for this guy. Alright then‚ what is the definition of a planet? In the dictionary

only the rocky worlds of the inner Solar System and the gas giants of the outer system will be “named”as “planets”. The “inner Solar System” is the region of space that is smaller than the radius of Jupiter’s orbit around the sun. It contains the asteroid belt as well as the terrestrial planets‚ Mercury‚ Venus‚ Earth‚ and Mars. The “gas giants” of course are Jupiter‚ Saturn‚ Neptune‚ and Uranus. So now we have eight planets instead of the nine we used to have. Pluto is made up mostly of ice and

Astronomy 3/21/13 Deep Space Disposal "Why not just get rid of radioactive waste and other trash by simply shooting it into space?" This question has passed peoples lips before but has never been a major subject. I personally think that this would work perfectly; it would eliminate the need to dispose of trash in other‚ more harmful ways. It would also reduce the litter and trash that is literally covering our planet. Sure there are facilities that specialize in getting rid of trash. There
