Its unusual orbit carries it extremely close to the sun on Nov. 28, 2013. Around this time, comet ISON may become bright enough to glimpse in the daytime just by blocking the sun’s glare.  \nComet ISON follows such an eccentric and steeply angled orbit that it can be difficult to picture how it relates to the orbits of the inner planets. This paper model illustrates the comet’s path during its six-month trek in the vicinity of Earth, Venus and Mercury. Track  \nhow the relationship between Earth and the comet constantly changes by referring to the dates along both orbits.  \nThe top of the model’s Display Base represents the plane of Earth’s orbit around the sun. The comet spends less than a month south of (below) this plane as it whips around the sun.  \nLong ago, perhaps due to the gravitational influence of a passing star, comet ISON was nudged out of the Oort cloud, a storage zone at the fringes of the solar system that may hold a trillion comets. ISON fell toward the sun along an elongated path  \nComet ISON is making its way through the inner solar system. Visualize its unusual orbit and track its journey around the sun with this paper model. The background image shows comet NEAT (C/2001 Q4) during its 2004 appearance. Background: T. A. Rector (Univ. of Alaska Anchorage), Z. Levay and L. Frattare (STScI) and WIYN/NOAO/AURA/NSF  \n[www.nasa.gov](www.nasa.gov)  \nComet ISON floats against a backdrop of stars and galaxies in this composite image, acquired April 10, 2013, by the Wide Field Camera 3 instrument aboard the Hubble Space Telescope. At the time of this observation, the comet was 394 million miles from Earth. NASA, ESA, and the Hubble Heritage Team (STScI/AURA)  \nthat is quite unlike the nearly circular orbits of the inner planets. The planets travel in orbits only slightly tilted out of Earth’s orbital plane, but ISON’s track is steeply inclined to it. Based on the details of its orbit, astronomers think this is ISON’s first passage through the inner solar system and near the sun.  \nComet ISON will pass about 6.7 million miles (10 .8 million km) from Mars on Oct. 1. That’s about six times closer than it will ever come to Earth, so scientists are planning to make intriguing observations using spacecraft now working at Mars, such as NASA’s Mars Reconnaissance Orbiter.  \nAlthough the orbit of Mars is not shown on the model, its location can be estimated. Using the scale on the Display Base, just measure down from the comet’s position on the date of its closest approach.  \nOn Nov. 28, comet ISON makes its sweltering swing around the sun, passing about 728,000 miles (less than 1.2 million km) above its visible surface. This incredibly close encounter is what classifies ISON as a “sungrazing” comet.  \nSatellites designed to study the sun, such as NASA’s Solar Dynamics Observatory, will be monitoring how ISON responds to the fierce solar heat. Scientists plan to use the comet’s tail as a solar probe to trace how hot gases move throughout the sun’s atmosphere, a region called the corona.  \nUsing data acquired by several space observatories, including NASA’s Swift and the Hubble Space Telescope, astronomers have estimated the size of the comet’s icy body to be about 3 miles (5 km) across. Scientists think this may be large enough for ISON to survive its fiery solar passage, but  \nthey cannot discount the possibility that the comet may break up into numerous small fragments that quickly evaporate. In fact, this is the typical fate of sungrazing comets.  \nIf ISON survives, it may be visible to the unaided eye in morning twilight during the first week of December. As it pulls away from the sun, the comet will quickly fade in brightness even as it comes closer to Earth. ISON makes its closest approach to Earth on Dec. 26, when it passes 39.9 million miles (6","cbCaivmXxKS4bSSa","https://ap.wps.com/l/cbCaivmXxKS4bSSa","pdf",4075649,"English","# Paper model of Comet ISON’s orbit\n## Comet ISON overview and orbital behavior\n## Assembly instructions\n## Classroom activity: how fast does a comet move?","[{\"question\":\"What is special about Comet ISON’s orbit in this model?\",\"answer\":\"The model emphasizes ISON’s steep, highly inclined trajectory relative to Earth’s orbital plane, making its path difficult to picture without the model.
