ExoplanetKyoto – an unique exoplanetary database has been launched from Kyoto University* in 2016 aiming to provide a more-symphatic exoplanetary image. Although, none of the exoplanetary images have been captured optically, over 3,900 confirmed exoplanets have been found by November 2018. There is a strong need to provide a typical illustration of these planets. Several different space authorities, including NASA, ESA, as well as independent organizations and artists have provided these images, however none of them provide imaginary pictures for all confirmed planets on the exoplanetary list.
We have created a series of textures that may fit scientific features and impressions for general comprehension of the public. In general, we classified the exoplanets according to their sizes and calculated their blackbody temperature. We have prepared a basic set of textures that may fit certain categories of the planets. In addition, specific features of individual planets are included, such as whether they are tidally locked or not, or whether they are covered by an ocean and vegetation, and if so, what colour. At the same time, there is a risk of providing a standard image for those planets without “real proof” simply because they might be wrong and false impressions to be given audiences. Nevertheless, since all information are not at scientificly confirmed, the images naturally contain “artistic impressions”  – in other words, the essense of art. In this field associated in Exoplanetary study, there are plenty of instances that require harmonized study between “pure science” and “arts”.
