The solar system probably formed about 4.5 billion years ago from a giant disk of gas, dust and ice in space. ... All forms of life on Earth require liquid water to survive, so the presence of liquid water is a good criterion for deciding whether other planets in the universe could be habitable. Earth is the only habitable planet in the solar system. Venus, closer to the Sun, is too hot to have liquid water. Planets and moons in the outer solar system are too cold for liquid water. ...

Testing the Automatic Detection of Directly Imaged Exoplanets Using Wavelet Analysis Chris Merchantz Introduction · Challenges associated with direct images of planets Distinguish planets in the following way: (1) a minimum flux threshold is from speckles maxima, anddefined for the features that are identified as local (2) the "Exoplanet Recognition Using a Wavelet Analysis Technique" Fig. ... This spectrum is used as template spectrum to recognize planets in a deep image. ...

... Chapter 4: Solar System Targets > 4.2 Target Identification . ... The following information is required to identify and classify each target. ... For example, separate targets should be defined if you plan to take spectra of several different surface features on a planet, or if you plan to observe the same feature with different timing constraints. ... Description . PLANET . If the target is the center of a planet, enter PLANET followed by its name (e.g., PLANET JUPITER , PLANET SATURN ). ...

Present section contains two Tables: the first one lists the names of all minor planets in alphabetic order as of the last updating of the Table. ...

... Satellites of the planets are assigned a provisional designation (indicating year of discovery) by the Central Bureau for Astronomical Telegrams ( CBAT ) upon satisfactory demonstration of the existence of a new object. ... In the past, Comets were first given a provisional designation, consisting of the year and a lowercase letter indicating the order of discovery in the year (e.g., 1994a was the first comet discovered or recovered in 1994, 1994b the second, etc.) ...

... In the following examples I will use pulsar 1842-04 to which I have added a model planet in order to illustrate what the data tells us. ... Alpha high is for the white noise power law and alpha low is for the red noise power law. ns is effectively the bin size. ... In the graphs on figure 2 the outer lines are the model, so you can see where and when the data fits the model and when it doesn't. A peak in the data corresponds to a peak in the top graph of figure 3, i.e. a planet. ...
