Description

From the listing uploaded by “appupdater”.

This is a scientific application that simulates the solar system dynamics using the information provided by the NASA NEO Program. The Near Earth objects and objects close to other planets will be reported in real time. The advanced graphical interface allows you to monitor the orbits of celestial bodies as a function of the elapsed time. X rays and protons emitted by Sun are also notified to have a complete view of the dangers from space. FEATURES ● User friendly graphical interface ● Sky view mode ● Sensor targeting ● Spherical coordinates of selected objects ● 2 Notification levels basing on severity or proximity to the Earth ● Notification of objects close to other planets ● Notification of solar wind events (X rays and protons) ● News regarding asteroids and scientific projects ● Detailed information of NEO (Size, Velocity, Distance, orbital period) ● Target links to space missions ● NEOs database updated every day FOR PRACTICAL REASONS ● The maximum resolution is achieved for asteroids that are less than 0.1 AU from the planets. The application photographs the situation on the current date and simulates events that will occur in the future or have occurred in the past. ● The number of asteroids plotted in the asteroid belt is only a fraction of the real number. ● The asteroids not yet included in the NASA NEO database may not be notified. ● X rays and protons levels are processed and saved continuously. The solar activity indicated as a significant event, has been inferred through the Statistical analysis of about 6 months of data sampling. The prediction will be improved with the increasing of data amount. NOTIFICATION CRITERIA: ● With the exception of the first notification, new notifications will be generated only if NEOs are approaching. The distance of the NEO to the planet must be at least 10% lower than that reported in the previous notification. ● NEO notifications have priority over solar notifications except for powerful events. Space is our next frontier.
