55 Cancri e, also known as Janssen, orbits a star – 3D Model
DISCOVERED 2004
PLANET TYPE: Super Earth
55 Cancri e , also known as Janssen , orbits a star called Copernicus only 41 light years away.
The molten surface is completely uninhabitable, but above the burning horizon, Janssen’s sister planet, Galileo, hangs in a dark sky. Silicates in the atmosphere would condense into clouds on the tidally-locked planet’s darkside reflecting the lava below. So, the skies would sparkle.

Detection Method: Radial Velocity
The radial velocity method measures slight changes in a star’s velocity as the star and the planet move about their common center of mass. Astronomers can detect these variances by analyzing the spectrum of starlight. In an effect known as Doppler shift, light waves from a star moving toward us are shifted toward the blue end of the spectrum. If the star is moving away, the light waves shift toward the red end of the spectrum. This happens because the waves become compressed when the star is approaching the observer and spread out when the star is receding. The effect is similar to the change in pitch we hear in a train’s whistle as it approaches and passes.

Detection Method: Transit
If a planet passes directly between a star and an observer’s line of sight. It blocks out a tiny portion of the star’s light. Thus reducing its apparent brightness. Sensitive instruments can detect this periodic dip in brightness. From the period and depth of the transits. The orbit and size of the planetary companions can be calculated. Smaller planets will produce a smaller effect, and vice-versa. A terrestrial planet in an Earth-like orbit, for example, would produce a minute dip in stellar brightness that would last just a few hours.

In 2019 the presence of water vapour in K2-18b’s atmosphere was discovered, drawing attention to this system. Its atmosphere may have an unexpectedly small concentration of methane, although observation uncertainties preclude a definitive determination. K2-18b has been studied as a potential habitable word that, temperature aside, resembles more a gas planet like Uranus or Neptune than Earth.

I am here to share my knowledge of Topography and especially Contour Maps in Google Earth Pro, I remember my first steps with Google Earth, I placed my tiles one by one over several kilometers to make a whole of around 50 square kilometers. (32 square miles). Today we have the files easily found on the internet, luck at hand, of course I’m talking about our famous files (KML and KMZ) that I offer you for free on my website, courtesy of all it’s good developer (Google, NASA and several other people who often work in the shadows). I am an outdoor fisherman and I have used a lot of good old monochrome topographic maps which still help out very well. I offer free whatever links and KML files. Good hack and if by mistake or interest you click on one of my ads, I won’t blame you! Here are the links and files:

) 55 Cancri e ( abbreviated 55 Cnc e, formally named Janssen /ˈdʒænsən/ ) is an exoplanet in the orbit of its Sun-like host star 55 Cancri A. The mass of the exoplanet is about 8.63 Earth masses and its diameter is about twice that of the Earth, thus making it the first super-Earth discovered around a main sequence star, predating Gliese 876 d by a year. It takes fewer than 18 hours to complete an orbit and is the innermost-known planet in its planetary system. 55
) Cancri e was discovered on 30 August 2004. However, until the 2010 observations and recalculations, this planet had been thought to take about 2.8 days to orbit the star. In October 2012, it was announced that 55 Cancri e could be a carbon planet.
) In February 2016, it was announced that NASA’s Hubble Space Telescope had detected hydrogen and helium (and suggestions of hydrogen cyanide), but no water vapor, in the atmosphere of 55 Cancri e, the first time the atmosphere of a super-Earth exoplanet was analyzed successfully.
I) In July 2014 the International Astronomical Union ( IAU ) launched NameExoWorlds.
A process for giving proper names to certain exoplanets and their host stars. The process involved public nomination and voting for the new names. In December 2015, the IAU announced the winning name was Janssen for this planet. The winning name was submitted by the Royal Netherlands Association for Meteorology and Astronomy of the Netherlands. It honors the spectacle maker Zacharias Janssen who is sometimes associated with the invention of the telescope.
J) Like the majority of extrasolar planets found prior to the Kepler mission.
55 Cancri e was discovered by detecting variations in its star’s radial velocity. This was achieved by making sensitive measurements of the Doppler shift of the spectrum of 55 Cancri A. At the time of its discovery, three other planets were known orbiting the star. After accounting for these planets, a signal at around 2.8 days remained, which could be explained by a planet of at least 14.2 Earth masses in a very close orbit.

New layers set in Google Earth Pro!
Today we’ve started to roll out updated map layers in Google Earth Pro on desktop.
With this change we are removing some outdated data in Earth Pro, as well as making improvements to keep maps layer data more consistent with other:. Google products like Maps and Earth web and mobile.
The older layers will be phased out over the next few months and will be labeled as “outdated” during the interim until they are permanently removed. Offline use: The new map layers are not cached persistently and therefore will not work offline.
This might result in temporary gaps in coverage when rapidly panning the map or zooming in and out, but overall results in faster map load times.
