Top 10 records ranked by the probability listed for each date. Probabilities are not added together.
Probability means the estimated chance for the specific impact scenario shown in one row. A value such as 0.01% is a one-in-10,000 chance for that scenario; it is not a prediction that an impact will happen.
Quick definitions: median is the middle value after sorting; Palermo Scale compares a scenario's risk with the background risk from objects of similar size.
The uploaded file does not include an asteroid name or usable Earth-distance / impact-width values. Those fields are intentionally shown as unavailable. Palermo values are logarithmic comparisons with background risk; Torino values are a separate 0–10 public communication scale.
How to read the columns: Potential impact date = the modeled date of a possible encounter; Probability = chance for that row's scenario; Energy (Mt) = estimated impact energy; Palermo = technical comparison against background impact risk (negative values are below background); Torino = 0–10 public hazard scale.

Scientific note: This is an analysis of a saved Sentry monitoring export, not a live risk assessment. Each probability belongs to an individual listed date/solution. Do not sum the probabilities: the records may be related solutions for the same object. A Torino Scale of 0 means the listed scenario is below the scale's threshold for concern; it does not mean the object has zero probability. The CSV does not identify the asteroid, so this dashboard does not assign it a name.

Move the slider to calculate the asteroid's approximate position before or after the catalog reference date. The animation advances simulated days, not real-time days.
How to read this map: The Sun is at the center. The blue dashed circle is Earth's 1 AU orbit. The orange curve is the selected asteroid's calculated orbit; the orange dot is its position at the chosen date. AU (astronomical unit) is the average Earth–Sun distance, about 150 million km. This is a top-down 2D view, so inclination above/below Earth's orbital plane is not visible here.
Why are these called NEO candidates? This local subset was selected using perihelion distance q < 1.3 AU. That means the orbit comes within 1.3 times Earth's average distance from the Sun at its closest point. It is a catalog filter, not proof of an Earth crossing or collision risk.
Model limitations: The plotted path is calculated from the catalog's osculating Keplerian elements at epoch 2026-09-17. It is a two-body approximation, not an N-body ephemeris; it does not include planetary perturbations or predict an Earth impact. The catalog's perihelion-distance filter q < 1.3 AU is used to select near-Earth-object candidates. It does not mean these objects are on a collision course.
