Do the Galactic Coordinates have the Sun on the Galactic Latitude=0 as the Sun and Earth Elliptic? I understand that RA and DEC are Sun based quantities and are just points of reference. I am just looking for a mathematical model in RA and DEC for how the Milky Way goes across the sky. Here are the ...

I am referring to the center of mass or galactic ecliptic type (not with the sun) centerline of the galaxy.

The Milky Way Galaxy encircles the globe with its gas and debris. The center of the galaxy is at "Sagittarius A" located at a distance of 35,900 ly @ Right Ascension = 266.417 deg and 29.00781 deg. It propagates out from there and encompasses our solar system and beyond. We are on the oute...

A craft has two types of drag: subsonic and supersonic (below and above the speed of sound). Also factoring in is the amount of roll the craft has. In Subsonic the Force of drag is: Fd = Cd * airdensity * velocity^2 / 2 * Area where Cd is the drag coefficient airdensity is 0.001275g/cm^3 at equatori...

On 1-4-12 the Earth reached its Perihelion.

The closest Earth's radius to the Sun.

I have a few sources that have conflicting accounts about the time this happened.

Could someone give me a definitive source to clarify my discrepancies.

Comet Lovejoy just missed being consumed by the Sun. Its original trajectory took it just fraction of a solar radius from our Sun emerging on the other side. Here are a few Images from the Solar and Heliospheric Observatory (SOHO) from yesterdays occurrance: http://www.pcmag.com/article2/0,2817,2397...

How many Man-Made Satellite not in Earth Orbit are there.

Examples: Dawn, Pioneer and Voyager

What is the name of the crater on the moon that has mysterious magnetic properties?

Was this a charged particle from space or is the Moon generating it?

Can this solve our power generation quandry on Earth?

We have put Rovers on Mars. We have made vehicles that can drive many miles without Human intevention. We have orbited and landed automously on other planets. As Steven Hawking say not too long ago: Why cannot we begin extrasolar travel? Traveling closer to the speed of light we could reach a close ...

"Chris Peterson Wrote: If you need more accuracy in your calculations, you should not be using Keplerian elements at all, but a more complex system, using either series with many terms or dynamic integration. Could you please elaborate on the above methods. I am college educated ie Calculus an...

For now I will stick with Keplerian Classical Elements. I knew about both sites previously mentioned. They do give equations and the final results of RA,DEC,eclLong, etc. They both do not give the correct Keplerian data (listed above) for a specific times.

I have developed a program calculating the orbits of the planets from Jet Propulsion Lab (JPL) data. I am in need of the actual data of the planet's orbits for specific dates : Argument of the Perihelion True Anomaly Mean Anomaly Semi-Major Axis Eccentricity Longitude of the Ascending Node etc If so...

When a Star reaches the end of its Giant stage, ie when it runs out of availiable Hydrogen, it implodes. If the mass of the Star is over 12 times the mass of the Sun it creates a Supernova with a Black Hole as its center. Below 12X limit it forms a Planetary Nebula. Below 1.4 times the Solar Mass it...

Earth currently passes into the northern hemisphere of the sun ~11.26° prior to vernal equinox (on around March 9th). I think you said on March 9 the orbit had a Sun longitude ~11.26 Degrees but no Sun latitude. Is there any way of getting this kind of information? Do the Periapsis, Apoapsis and Ve...

In reguards to the Keplerian Orbit I am concerning with the orbit related to angles not using the Ecliptic but instead the orbit with the angles of the distance from the Sun's Equator. I am really interested how the Vernal Equinox points in a 3D orbit relative to the Sun. I know it points somewhere ...

Earth orbits about 7 Degrees above the Equator of the Sun. Can we discuss the actual orbit in Keplerian Data around the Sun's Equator and how the orbit relates to the Vernal Equinox.
