"What is a Sungrazing Comet?", "description": "Sungrazing comets are a special class of comets that come very close to the sun at their nearest approach, a point called perihelion. To be considered a sungrazer, a comet needs to get within about 850,000 miles from the sun at perihelion. Many come even closer, even to within a few thousand miles. Being so close to the sun is very hard on comets for many reasons. They are subjected to a lot of solar radiation which boils off their water or other volatiles. The physical push of the radiation and the solar wind also helps form the tails. And as they get closer to the sun, the comets experience extremely strong tidal forces, or gravitational stress. In this hostile environment, many sungrazers do not survive their trip around the sun. Although they don't actually crash into the solar surface, the sun is able to destroy them anyway. Many sungrazing comets follow a similar orbit, called the Kreutz Path, and collectively belong to a population called the Kreutz Group. In fact, close to 85% of the sungrazers seen by the SOHO satellite are on this orbital highway. Scientists think one extremely large sungrazing comet broke up hundreds, or even thousands, of years ago, and the current comets on the Kreutz Path are the leftover fragments of it. As clumps of remnants make their way back around the sun, we experience a sharp increase in sungrazing comets, which appears to be going on now. Comet Lovejoy, which reached perihelion on December 15, 2011 is the best known recent Kreutz-group sungrazer. And so far, it is the only one that NASA's solar-observing fleet has seen survive its trip around the sun. Comet ISON, an upcoming sungrazer with a perihelion of 730,000 miles on November 28, 2013, is not on the Kreutz Path. In fact, ISON's orbit suggests that it may gain enough momentum to escape the solar system entirely, and never return. Before it does so, it will pass within about 40 million miles from Earth on December 26th. Assuming it survives its trip around the sun. || ", "release_date": "2013-07-16T13:00:00-04:00", "update_date": "2023-05-03T13:52:00.158074-04:00", "main_image": { "id": 463840, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a011300/a011307/Sungrazer_Still.png", "filename": "Sungrazer_Still.png", "media_type": "Image", "alt_text": "Short, narrated video about sungrazing comets.Watch this video on the NASAexplorer YouTube channel.For complete transcript, click here.", "width": 1280, "height": 720, "pixels": 921600 } }, { "id": 11145, "url": "https://svs.gsfc.nasa.gov/11145/", "page_type": "Produced Video", "title": "Counting Comets", "description": "As comets orbit the sun, many come too close and evaporate completely. Others survive the journey, but their orbits gradually move closer to the sun. Ultimately, the heat of the solar atmosphere melts the ice that binds a comet together and breaks it apart into smaller bodies that follow similar orbits. These are the sungrazers, and scientists and amateur astronomers are seeing more of them than ever. As of 1979, we only knew of a dozen. Nearing the end of 2012, thanks to better observation tools, we have now seen 3,000. The bulk of the sungrazers are known as Kreutz comets, and are likely derived from a single original comet observed as early as 371 AD.

SOHO allows us to see smaller, fainter comets closer to the sun than we have ever been able to see before.

Finding a comet before it moves into view of space-based telescopes gives scientists the opportunity to prepare their instruments to make the best possible observations. The sungrazing comet—named Lovejoy, or C/2011 W3 in the technical vernacular—ultimately crossed the sightlines of the mirrors and lenses on no less than five satellite observatories. And the results were spectacular. As it moved toward the sun, many comet-watchers predicted it would evaporate as it flew within 87,000 miles of the roiling hot surface. But comet Lovejoy elated spectators when it survived its death-defying trip and re-emerged on the other side, as shown in the first video below, captured by NASA's Solar Dynamics Observatory (SDO) satellite on December 15, 2011. || ", "release_date": "2012-01-19T00:00:00-05:00", "update_date": "2023-05-03T13:53:19.503231-04:00", "main_image": { "id": 479866, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a010800/a010895/Lovejoy_near_sun_1024x576.jpg", "filename": "Lovejoy_near_sun_1024x576.jpg", "media_type": "Image", "alt_text": "Space telescopes capture Comet Lovejoy's dangerous encounter with the sun and its journey beyond.", "width": 1024, "height": 576, "pixels": 589824 } } ], "sources": [ { "id": 13623, "url": "https://svs.gsfc.nasa.gov/13623/", "page_type": "Produced Video", "title": "Four of Our Favorite SOHO-discovered Comets", "description": "Karl Battams, manager of NASA's citizen science Sungrazer Project, talks about his four favorite comets that SOHO has observed.Music: \"Inducing Waves\" from Universal Production MusicWatch this video on the NASA Goddard YouTube channel.Complete transcript available. || 13623_SOHO4FavoriteComets_ProRes_1920x1080_2997.01026_print.jpg (1024x576) [155.4 KB] || 13623_SOHO4FavoriteComets_ProRes_1920x1080_2997.01026_searchweb.png (320x180) [72.1 KB] || 13623_SOHO4FavoriteComets_ProRes_1920x1080_2997.01026_thm.png (80x40) [5.3 KB] || 13623_SOHO4FavoriteComets_ProRes_1920x1080_2997.mov (1920x1080) [3.1 GB] || 13623_SOHO4FavoriteComets_1080.mp4 (1920x1080) [245.9 MB] || 13623_SOHO4FavoriteComets_Good_1080.mp4 (1920x1080) [128.8 MB] || 13623_SOHO4FavoriteComets_1080.webm (1920x1080) [27.2 MB] || SOHO_4000Comets_SRT_Captions.en_US.srt [4.8 KB] || SOHO_4000Comets_SRT_Captions.en_US.vtt [4.8 KB] || ", "release_date": "2020-06-17T10:00:00-04:00", "update_date": "2023-05-03T13:44:54.843024-04:00", "main_image": { "id": 385045, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a013600/a013623/13623_SOHO4FavoriteComets_ProRes_1920x1080_2997.01026_print.jpg", "filename": "13623_SOHO4FavoriteComets_ProRes_1920x1080_2997.01026_print.jpg", "media_type": "Image", "alt_text": "Karl Battams, manager of NASA's citizen science Sungrazer Project, talks about his four favorite comets that SOHO has observed.Music: \"Inducing Waves\" from Universal Production MusicWatch this video on the NASA Goddard YouTube channel.Complete transcript available.", "width": 1024, "height": 576, "pixels": 589824 } }, { "id": 13622, "url": "https://svs.gsfc.nasa.gov/13622/", "page_type": "Produced Video", "title": "Counting Comets", "description": "Music Credit: Birds in The Rain by Robert GuerrierComplete transcript available.Watch this video on the NASA Goddard YouTube channel. || cometthumb.jpg (1920x1080) [404.7 KB] || cometthumb_print.jpg (1024x576) [192.3 KB] || cometthumb_searchweb.png (320x180) [56.6 KB] || cometthumb_web.png (320x180) [56.6 KB] || cometthumb_thm.png (80x40) [5.1 KB] || 13622.Counting_Comets.Mobile720.mp4 (1280x720) [108.5 MB] || 13622.Counting_Comets.Twitter1080.mp4 (1920x1080) [40.1 MB] || 13622.Counting_CometsFB.mp4 (1920x1080) [215.9 MB] || 13622.Counting_Comets.YouTube1080.mp4 (1920x1080) [284.3 MB] || 13622.Counting_Comets.YouTube1080.webm (1920x1080) [20.2 MB] || Counting_CometsAPR.mov (1920x1080) [4.4 GB] || 13622Comets.en_US.srt [3.6 KB] || 13622Comets.en_US.vtt [3.7 KB] || ", "release_date": "2020-05-19T10:00:00-04:00", "update_date": "2023-05-03T13:44:57.683699-04:00", "main_image": { "id": 385035, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a013600/a013622/cometthumb.jpg", "filename": "cometthumb.jpg", "media_type": "Image", "alt_text": "Music Credit: Birds in The Rain by Robert GuerrierComplete transcript available.Watch this video on the NASA Goddard YouTube channel.", "width": 1920, "height": 1080, "pixels": 2073600 } }, { "id": 4343, "url": "https://svs.gsfc.nasa.gov/4343/", "page_type": "Visualization", "title": "Lots of Comets -
