Chronololgical listing of objects making close approaches to Earth between 1994 and 2005.

The Near-Earth Object Wide-field Infrared Survey Explorer Reactivation Mission (NEOWISE; Mainzer et al. 2014, ApJ, 792, 30) is a NASA Planetary Science Division space-based survey to detect, track and characterize asteroids and comets, and to learn more about the population of near-Earth objects that could pose an impact hazard to the Earth. NEOWISE systematically images the sky at 3.4 and 4.6 μm, obtaining multiple independent observations on each location that enable detection of previously known and new solar system small bodies by virtue of the their motion. Because it is an infrared survey, NEOWISE detects asteroid thermal emission and is equally sensitive to high and low albedo objects.The Known Solar-System Object Possible Associations List is a compendium of asteroids, comets, planets or planetary satellites, with orbits known at the time of NEOWISE data processing, that were predicted to be within the field-of-view at the time of individual NEOWISE Single-exposures. Individual objects were observed multiple times, so may have multiple entries in the list. When the predicted position of a solar system object is in proximity to a detection in the NEOWISE Single-exposures, the NEOWISE detection position and brightness information are also provided.

The DENIS program (Deep European Near-Infrared southern sky Survey) was a ground-based survey of the southern sky with the aim of providing an extensive I,J,Ks photometric catalog of point and extended sources. It was carried out at the 1.0 meter ESO telescope at La Silla, Chile from late 1995 through the end of 1999. This data set contains the DENIS I,J,Ks photometry for 2000 known asteroids identified in the DENIS catalog.

Because it is an infrared survey, NEOWISE detects asteroid thermal emission and is equally sensitive to high and low albedo objects.The following table contains brief descriptions of all metadata information that is relevant to the processing of Single-exposure (level 1) images and the extraction of sources from the corresponding Single-exposure images. The table contains the unique scan ID and frame number for specific each single-exposure image and the reconstructed right ascension and declination of the image center. Much of the information in this table is processing-specific, and may not be of interest to general users (e.g. flags indicating whether frames have been processed or not, and the date and time for starting of the pipeline etc). The metadata table also contains some characterization and derived statistics of the Single-exposure image frames, basic parameters used for photometry and derived statistics for extracted sources and artifacts. For example, it contains the number of sources with profile-fit photometry Signal-to-Noise (SNR) greater than 3, and the total number of real sources affected by artifacts such as latent images and electronic ghosts.

Because NEOWISE scanned the same region of the sky multiple times, the Single-exposure Database contains multiple, independent measurements of objects. Positions, magnitudes in the two NEOWISE bands, astrometric and photometric uncertainties, flags indicating measurement quality, the time of observations and associations with the AllWISE Source Catalog and 2MASS Point Source Catalog are presented for entries in the Database.

'The USGS Earth Resources Observation and Science (EROS) Center archive holds data collected by the Landsat suite of satellites, beginning with Landsat 1 in 1972. '

NeoWs (Near Earth Object Web Service) is a RESTful web service for near earth Asteroid information. With NeoWs a user can: search for Asteroids based on their closest approach date to Earth, lookup a specific Asteroid with its NASA JPL small body id, as well as browse the overall data-set.

'Spaceborne Imaging Radar-C (SIR-C) was part of an imaging radar system that was flown on board two Space Shuttle flights (9 - 20 April, 1994 and 30 September - 11 October, 1994). The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center distributes the C-band (5.8 cm) and L-band (23.5 cm) Survey Data. A total of about 50 hours of data, corresponding to roughly 50 million square kilometers of ground coverage, were collected during each mission. The ground swath width varies from 15 to 90 kilometers depending on the imaging mode and incidence angles of the radar beams. All science data were processed into Survey products. The Survey product is intended as a \"quick look\" browsing tool for viewing the areas imaged by SIR-C. This product is not designed to be used for quantitative scientific analysis. Survey Data consists of a frame image of a data segment, which represents a subset of the data swath. Resolution is approximately 100 meters, processed to a 50-meter pixel spacing. Additional information on SIR-C is available at: http://southport.jpl.nasa.gov.'
