Mercury (Budha Graha) is a planet for communication and cognitive functions that behaves in different ways, depending on the sign where it is found on a chart. Mercury rules the rational mind and is involved in learning processes; it concerns thinking, orality, and different types of language, verbal or not.
The position of Mercury in our birth chart reveals how we express our ideas, how we communicate with others, and how we understand the messages we receive from others. It is important to emphasize that communication on Mercury is not restricted to speech. It can flow in written form or also through reasoning.
Scientific Significance of Mercury Transit
When Mercury comes between Sun and any superior planet, the Mercury transit occurs which happens only 13 times per century. The special thing about this planetary transit is that you will observe small fractures of the solar eclipse before that. It will require a telescope or binoculars, not without a solar filter. The mercury looks like a dark spot passing through a Sun’s surface and it seems like the spot is wet with a drop extending from the body (black drop effect).
Some scientific investigations from Mercury transit observations are:
- Solar system scale Measurement,
- Rotation of Earth and Moon’s tidal acceleration inspection,
- Venus mass calculation using secular variations in Mercury’s orbit,
- Solar radius Long-term variation inspections,
- Black drop and gray drop inspections, and
- Exoplanet transit reference.
Previous transit events of Mercury
Pierre Gassendi, a french astronomer, was the first person to observe this significant event, and later a German Astronomer Johannes Kepler was astonished to see the size of the planet compared to the Sun. The royal observatory Shuckburgh telescope was used to inspect the celestial event of the 1832 Mercury planet transit.
A total of four mercury transits have occurred in this century, particularly in 2003, 2006, 2016, and 2019. The Mercury transit of 2016 has a high-resolution timelapse from a major solar telescope of Solar Dynamics Observatory. The observed transit times for variable locations varied by 3 minutes due to parallax.
