Euclid is a medium class mission designed to study the geometry of dark universe. It will work in the visible and near infrared imaging & spectroscopy for a lifetime of 6 years down to the magnitude of mAB = 24.5 with Visible Imager Instrument (VIS) and mAB = 24 with Near Infrared Spectrometer and Photometer instrument in Y, J & H broadband filters. The current survey design will avoid ecliptic latitudes below 15 degrees, but the observation pattern in repeated sequences of four blocks with four broad-band filter seems well-adapted to Solar System object detection. The aim of this thesis is to simulate the Solar System Objects (SSOs) for Near Infrared Spectrometer and Photometer (NISP) instrument and measure the flux/magnitude & position of these moving objects. The simulation of Solar System Objects is implemented in with simulator Imagem using the sky position, velocity, direction of movement and magnitude with respect to band of the objects. The length of the trail is determined using exposure time and after that the sky position is evolved for each band filter. The output images showed the trail of objects which is 2 to 10 pixels long in case of Near Infrared Spectrometer and Photometer instrument. To find out the flux distribution in the trail, the differential photometry is performed. The variation in magnitude was observed at least of 1% to 3% of the magnitude which may also implies that variation in brightness of objects can be observed with the velocity. To detect the moving objects, differential astrometry is also performed, which provides the catalogue with the information of position and proper motion of the objects as well as an image is also generated which showed the detected and undetected objects from all bands in one image.
