Transits Neptune

Notice that Saturn, the planet of restriction, is now in her fifth house of children, and Uranus, the planet of the unexpected, is in her eighth house of death and transformation. Those two transits, I should point out, aren t nearly enough to trigger such an exceedingly rare and terrible loss. After all, everyone who had an Ascendant in the neighborhood of 21° Virgo also experienced those transits. A birth chart must show the potential for an event in order for it to happen. And there it is The close opposition of her natal Uranus to her natal Sun, Moon, Mars, and Neptune clearly introduces the possibility of violence. The transits acted on the possibilities already there in her remarkable chart. 

Here s the rule The transits that pack the biggest wallop are those made by the slowest planets — Saturn, Uranus, Neptune, and Pluto — to the Sun, the Moon, the Ascendant, and the faster planets. Contacts made by the faster planets are usually short-lived. Contacts made by the slower planets to the slower planets (such as Uranus opposite your Pluto or Neptune conjunct your Saturn) may be too subtle to detect (unless the natal planet happens to occupy a prominent position in your chart). But contacts made by a slow planet to one of your personal planets — Pluto conjunct your Moon, Uranus opposite your Sun, and so on — signify the chapters of your life. 

Mars opposite Neptune Vivid dreams and artistic inspiration characterize this transit. But your efforts to get something done in the workaday world could go awry. You may feel taken advantage of, confused, or out of the loop. 

Neptune opposite Venus You feel riled up, especially (but not solely) about your love life. Romantic visions dance in your head, yet you re unwilling or unable to fulfill those dreams. This transit, like the conjunction of Neptune and Venus, stimulates wishful thinking in a big way. 

Neptune conjunct Saturn The rigid rules and regulations you live by aren t working anymore, and you need to update them with a more inspired, less fearful set of bylaws. Remind yourself that everyone who was born within a few months of you is experiencing this transit. And be sensible about money. 

Pluto opposite Neptune Unless you re well over 100 years old, this transit isn t one you have to worry about. 

Looking at that chart, I would have noticed that Saturn, the planet of lessons, was transiting back and forth over her Sun (and had twice made an exact conjunction with it earlier that year) that Uranus and Neptune, traveling in tandem in the ninth house, were conjunct her Saturn and opposed to her natal Pluto and that transiting Pluto had been dueling with her Ascendant for about a year and was approaching an exact opposition. 

The discovery of transiting planets with masses below 10 MEanh and radii consistent with rocky planetary models answered the important question as to whether planets more massive than Earth could be rocky. 10 Mgarth and 2 Earth radii are used as estimates from planet formation theories as the upper limit for rocky planet mass and size. For comparison, Uranus has about 14.5 MEanh and about 4 Earth radii. Above about 10 Earth masses a planet is thought to accumulate a substantial amount of gas that makes it akin to a gas giant with a substantial atmosphere, not a rocky planet with a thin outgassed atmosphere. Where exactly such a cut-off mass is that distinguishes rocky Super-Earths and gaseous Mini-Neptunes - if it exists at all - is an open question that mean density measurements of detected exoplanets currently explore. 

Atmospheres of extraterrestrial planets can be directly studied during a transit. Two transit events with the Near Infrared Camera and Multi Object Spectrograph (NIC-MOS) camera on the Hubble Space Telescope (HST) were observed for the object GJ 436 b. In order to detect the atmosphere, high-cadence time series of prism spectra covering the 1.1-1.9 pm spectral range were analyzed (Pont et al., 2009 [266]). This object is an extrasolar hot Neptune. The authors measured a flat transmission spectrum at the level of a few parts per 10000 in flux, with no significant signal in the 1.4 pm water band. 

Super-Earth planets are planets with masses between 1 and 10 Earth masses. Such masses are still beyond the mass of the gas giants, e.g. the mass of Neptune is 17 MEarth- The atmospheres of such objects may be different from atmospheres for typical terrestrial planets. Some of them may possess hydrogen rich atmospheres. These objects should show strong H2O features in their spectra. Objects that have lost most of their hydrogen could exhibit strong CO2 features. Generally, this type of objects seems to represent a transition between rocky objects and Neptune-like planets. The discovery of super-Earths was discussed e.g. in Elkins-Tanton and Sea-ger, 2008 [120]. They argue that there are three ways how such objects may obtain atmospheres ...
