Asteroids. Asteroids are objects, located in the A (region between the orbits of Maha_ and J while_). that orbits the Sun. Some of them are round, and others are irregular in shape. Some dre dozens or hundreds of kilometres across, but most are much smaller. Dwarf Planets. The largest object in the Asteroid Belt is called C . With a diameter of about 950 km. Ceres is referred to as a dwarf planet rather than an asteroid. Ceres is one of the five known dwarf planets in the solar system. The others are Pluto, Eris, Haumed, and Makemake. They are located far beyond N _. A dwarf planet is larger than an asteroid but smaller than a planet. Unlike a planet, a dwarf planet does not have enough g to pull all the rocky debris around it out of the path of its orbit. Comets. Comets are chunks of loosely held and I that come from the outer parts of the solar system. As a comet nears the Sun, the solar wind causes parts of the comet to vaporize and pushes them off the comet's surface. This forms what we call the 1 of a comet. Comets start their journeys toward and around the Sun when they are pulled from the outer regions of the solar system by the gravity of other objects. The orbits of comets bring them near the Sun with predictable regularity. For example, the orbit of Halley 4_ makes it visible to us on Earth every _26 years. Other comets have such huge orbits that they take thousands or millions of years to make one trip around the Sun. Meteoroids. Meteroids are chunks of rock, metal, or both that are shed from the a trends or comet. When a meteoroid enters Earth's atmosphere and starts to burn up, it makes a streak of light across the sky lasting a few seconds or shorter. This streak of light made by a meteoroid is called a metohite. Any part of the original object that survives the atmosphere and lands on Earth's surface is called a m Homework (WORKBOOK): 104, 105, + Planet Profiles Worksheets
