Can anyone explain what the heck that page means to a numb skull like me, please.
Completely confused as to what the data represents.
Would be greatly appreciated!!!
The large box on the left is showing the orbital elements of the asteroid. This is the information that is required to calculate the trajectory of the
asteroid as it moves through space.
The smaller box (Orbit determination parameters) provides details of the number of observations that have been used to calculate the orbital elements,
and the span of time between the first and last observations. "Opposition" is the point in an asteroid's orbit where it is directly opposite the Sun
in Earth's sky, so in this case you can see that this has happened 16 times between the dates of first and last observation. DE403 is the Digital
Ephemeris that has been used to calculate the positions of the planets in the timespan in which the asteroid has been observed. Each of the planets
exerts a small gravitational "tug" on the asteroid, and these forces need to be known precisely for very accurate orbit determination.
The Physical Parameter Table gives the absolute magnitude of the asteroid, which is the apparent magnitude that it would have as seen from Earth at a
distance of 1AU from our planet, 1 AU from the Sun, and with a 100% phase (in other words, fully illuminated). This is actually impossible, but it is
the "standard candle" that is used to compare the relative brightness of Solar System objects.
If you need any further information, please do not hesitate to ask
