Every close approach within 0.1 AU of Earth — date, distance, velocity, and whether it already happened or is upcoming. Possible use cases Datasource:

The analysis identified the 10 asteroids with the highest relative velocities during close approach. A bar chart and data table have been generated showing these asteroids ranked by their speed in km/s, with color intensity indicating velocity magnitude.

The analysis identified which asteroids make the most repeat close approaches to Earth. A bar chart was generated showing the top 20 asteroids ranked by their number of passes, giving a clear visual comparison of the most frequent visitors. Data tables were also produced with detailed breakdowns of approach counts per asteroid designation.

The analysis identified the 10 asteroids with the closest recorded approach distances to Earth, displayed in a bar chart and data table. The bar chart shows each asteroid's designation on the x-axis and their approach distance in kilometers on the y-axis, with darker red colors indicating closer approaches.

The bar chart and data table show a clear rise-and-fall pattern in asteroid close approaches from 2015 to 2035. Numbers climbed steadily from 1,127 in 2015, peaking at 2,661 in 2025, before dropping sharply to just 363 by 2035. The average across the full period is about 1,306 approaches per year.

There are 20 asteroids that combine both a very close approach distance (under 100,000 km) and a high velocity (over 20 km/s). These represent the most potentially notable near-Earth objects in the dataset — both nearby and fast-moving. A scatter plot and data tables have been generated showing their distances and velocities.

A line chart has been generated showing how the average asteroid approach velocity (in km/s) changes year by year from 2015 to 2035. The visualization plots each year's average velocity with markers, making it easy to spot trends, peaks, and dips across the two-decade span.

There are 21 unique asteroids with absolute magnitude below 22 (meaning they're relatively large objects) that have close approaches within 0.01 AU of Earth. A scatter plot and data table were generated showing all these encounters. The closest approach belongs to the famous 99942 Apophis, which will pass just 0.000254 AU (about 38,000 km) from Earth on April 13, 2029 — well within the orbit of geostationary satellites!

The analysis identified the 20 asteroids with the highest uncertainty in their close-approach distance estimates — measured as the gap between their minimum and maximum distance in AU. A bar chart and data table were generated showing these asteroids ranked from most to least uncertain.

Yes, there is clear monthly seasonality in close approach frequency. October is the busiest month with 3,328 approaches, while July is the quietest with only 1,410 — a 2.36x difference. A coefficient of variation of 25.1% confirms meaningful variation across months. A bar chart showing monthly totals across all years has been generated, along with supporting data tables.

A total of 1,221 close approaches occur within 1 lunar distance (dist lunar < 1). A bar chart has been generated showing the distribution of these close approaches by year, making it easy to spot which years had the most activity.

The analysis examined how many unique asteroid designations appear for the first time each year. A bar chart and supporting data tables were generated showing the count of new asteroid designations by year, giving a clear picture of discovery trends over time.

The analysis successfully identified the months and years with the highest concentration of asteroid close approaches. A bar chart was generated showing the Top 20 year-months with the most close approaches, and supporting data tables provide the detailed counts for each period. You can see which specific year-month combinations stand out as the busiest in the chart.

There are 330 asteroid close approaches that combine both top-10% velocity (≥17.56 km/s) and bottom-10% distance (≤0.005928 AU). These events span from January 20, 2015 to November 6, 2033. A bar chart has been generated showing how these extreme approaches are distributed by year across that timeframe.

The analysis successfully produced a visualization and data tables showing how the top 10 most frequently observed asteroids change their approach distances across successive visits. The interactive line chart plots each asteroid's distance in Lunar Distances (LD) for every visit, letting you see whether each asteroid gets closer or farther on repeat passes.

The analysis identified the 15 closest predicted asteroid approaches to Earth from today through 2035, ranked by distance in kilometers. A horizontal bar chart has been generated showing each asteroid's designation alongside its approach date, color-coded by distance (darker red = closer). Data tables are also available with full details including lunar distances and velocities.

The absolute magnitude (H) of asteroids in the dataset ranges from 13.82 to 34.06, with a median of 25.59 and a mean of 25.45. Using H < 22 as the standard threshold for potentially hazardous sizes (corresponding to a diameter of roughly 140 meters or more), only 1,864 asteroids — about 6.8% — fall into that category. The remaining 25,558 objects (93.2%) are smaller. Two visualizations were generated: a histogram showing the full magnitude distribution with the H=22 threshold marked, and a pie chart illustrating the hazardous vs. non-hazardous size split.

For potentially large asteroids (absolute magnitude H ≤ 22), the closest approach distance appears to be essentially independent of asteroid size. Across 1,886 large asteroid approaches, the correlation between absolute magnitude and approach distance is just -0.032 — extremely weak. Two visualizations were generated: a scatter plot showing the spread of approach distances across magnitude values, and a bar chart breaking down average approach distances by magnitude bins.

Closer asteroid approaches tend to have slightly HIGHER velocities compared to more distant ones. The closest 100 approaches average 12.67 km/s, while the farthest 100 average 11.20 km/s. However, the overall relationship is extremely weak (r = 0.0009), meaning distance alone is not a reliable predictor of velocity.
