# Solar System Barycenter Astrophysics 101

The Earth Doesn’t Actually Orbit The Sun?

You were taught that Earth and other planets in our solar system orbit the sun, and that our solar system orbits the center of the Milky Way. Did your science teacher have it wrong? Is everything you’ve learned about physics and gravity wrong?

The Earth Doesn’t Actually Orbit The Sun?

For all practical purposes, what you were taught wasn’t entirely wrong. The Earth does in fact orbit the sun. In the strictest sense, however, it doesn’t.

The sun and other planets each have their own gravity well which interact and pull on one another. The result of this, is that everything in an orbital system (like our solar system) orbit the center of mass of the system. This ‘center of mass’ is called the barycenter. The Earth, the sun and everything else in our solar system orbit this barycenter – not the sun.

Where Is The Barycenter?

In a single star system like ours, most of the time (but not always), the barycenter is located somewhere within the star itself. However, most barycenters continuously change as massive objects (like planets) orbit a star.

If an unusual alignment happens where a large percentage of mass is on one side of the star, the barycenter can exist outside of the star’s radius. In cases of 2 star systems, the barycenter will be located between the two stars. If the stars aren’t of the same mass, it will be closer to the heavier, or more massive one.

Now you will note in the diagram that there is a coordinate system (x y axis) to the far right on the x axis is the First point of Aries 0 degrees celestial longitude. You will also note a faint dashed white line that is the circumference or outer edge of the Sun. So the solar system barycenter and the sun’s location are dependent on the motion of the planets and other massive objects in the solar system.

And if you want all the gory detailed data re the position down to the .00000001 of a degree longitude you can go tohttp://www.cv.nrao.edu/~rfisher/Ephemerides/ephem_descr.html#eph_cont .

Now your first assignment is to go and find on the attached chart where the SSBC solar system barycenter is in 2014. Your next task will be to have a look at its path for the next few years say up to 2017.  The location of the SSBC for the period 2000-2050 (courtesy of L McNish) is shown in the black chart.

A dotted white circle indicates the circumference of the Sun. A segment (red line) in this chart indicates the path of the SSBC during the year 2016 at radius of 1. You will note that the SSBC traverses near and though the circumference of the Sun during 2016, similar to the SSBC passage in 2005 a year with a number of major hurricanes. In the next post I will be uploading the cosmic footprints for the dates during the 2016 hurricane season where the solar, lunar and galactic configurations are similar to those where past major events occurred.

Here endeth the lesson.

# Location of Solar System Barycenter and Major North Atlantic Hurricanes

Please find below a diagram showing the celestial location (Cosmic Footprint) of the barycenter of the solar system with respect to the center of mass of the Sun at the time of the Atlantic Hurricanes which have had a central pressure of less than or equal to 910 mb, major Cat 5 cyclonic activity.

The graph shows the location of the barycenter (red and black dots) at the time of the major Cat 5 activity. The red circle is the circumference/surface of the Sun at a radius of 1. The plane of the diagram is coincident with the plane of the ecliptic. All the distances of the barycenter at the instants of the above cyclonic activity are based on the above unit which has been calculated by the NASA Horizons Group.http://ssd.jpl.nasa.gov/?horizons. The direction of the barycenter from the Sun’s center is shown in relation to the First Point of Aries.

So we have 8 out of the 11 hurricanes in question occurring when the distance between the barycenter and the mass center of the Sun is ~ 1 or when the barycenter of the solar system is near the surface of the Sun.

# 2016 North Atlantic Hurricane Season

Observations of the extreme Atlantic hurricanes have shown that 8 of 11 of the major cyclonic events occurred when the SSBC is at or near a distance of 1 radius of the Sun from the center of the Sun (or at or near its surface). Given the previous posts re cyclonic activity and the location of the Solar System Barycenter, this post identifies the next hurricane season (2016) which has the potential for major cyclonic activity.

Recent work on the Lagrangian Points L4 and L5 points as well as the location of the moon and line nodes has opened the possibility that for the 2016, 2032 and other potential major hurricane seasons we may be able to identify the days during those seasons with the potential for extreme cyclonic activity.

So what can we observe about the 2016 hurricane season. It could be a long season with the first configuration occurring in late May on the 26th and the last one occurring on November 4th. The dates shown on the charts are not predictions for hurricane activity. They are configurations which are similar to where the maximum intensity of other major events have occurred. Hence, if a hurricane is in progress when one of these configurations occurs there is a possibility that it might reach its maximum intensity at or near the instant of the configuration.

One series of the configurations, which is of particular interest, is the three charts from August 27-September 1-September 6. The moon (blue line) will move counter clockwise from the L5 point to the L4 point (black lines) through the line of nodes (magenta line) which is conjunct with the Solar Earth axis during this motion. This configuration could be the basis for a hurricane to maintain its intensity for a number of days.

This series of configurations as well as the other charts that have been uploaded all occur when the SSBC is at a distance near or equal to 1 which is the reason the 2016 season has been identified as a possible severe hurricane season.

We are not suggesting that severe Atlantic cyclonic activity will not occur during the 2014 and 2015 seasons or after 2016. We are saying that the 2016 season best fits our observations sub 910mb North Atlantic cyclonic activity.

# Predicted Bay of Bengal Cyclone

Analysis of 10/18/15 12:00 UT Window

10/18/15 was identified as a possible window for a major cyclone in the Bay of Bengal because the Solar System Barycenter (SSBC) on the above date is in opposition or at 90 degrees to previous instants when a Category 5 cyclone was present in the Bay of Bengal in 2013 and 1999. So using the location of the SSBC as the primary criteria, we examine the SSBC data from the Jet Propulsion Laboratory for the date when the SSBC will be at ~191 degree (90 degrees to the SSBC at the SSBC in October 2013 and ~180 degrees to the SSBC in October 1999. 10/18/15 was identified as date meeting that criteria.

Calculating the longitudes of the moon, sun and line of nodes for 10/18/15 at 12:00UT resulted in the above Cosmic Footprint Chart. The Sun is near conjunction with the SSBC, the moon is conjunct with the center of the galaxy and orthogonal to the line of Nodes, the line of Nodes is orthogonal to the center of the galaxy. And very importantly, similar to the 2013 and 1999 cyclone events, the moon is in conjunction with La Grangian L4 point of the La Grangian field between the Earth and the Sun. The axis from the center of the Earth to L4 is also orthogonal to line of Nodes.
