Vhils is the tag name of Portuguese graffiti/street artist Alexandre Manuel Dias Farto. Alexandre Farto was born in Portugal in 1987, he studied at the Byam Shaw School of Art in London. Vhils works in London and Lisbon, he gained prominence when his work of a face carved into a wall appeared alongside a picture by street artist Banksy at the Cans Festival in London in 2008. A photograph of him creating the work appeared on the front page of The Times, he was given space to show his work by Banksy's agent, Steve Lazarides. Several of his works were published in 2008, he is shown by Vera Cortes and the Magda Danysz Gallery. During Fremantle's 2013 Fremantle Street Arts Festival, the Norfolk Hotel was decorated with an original image of the first Australian female senator; the image of Dame Dorothy Tangney DBE was created by his assistants. Luxembourg Freeport, an art storage facility opened in 2014, includes a large mural by Vhils, etched into one of the atrium concrete walls. Vhils has taken to several places of the world, trying to reveal the stories inside the walls.

(285263) 1998 QE2

1998 QE2, provisional designation 1998 QE2, is a dark asteroid and synchronous binary system, classified as near-Earth object and hazardous asteroid of the Amor group 3 kilometers in diameter. It was discovered on 19 August 1998, by astronomers of the LINEAR program at Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, in the United States, its sub-kilometer minor-planet moon was discovered by radar on 30 May 2013. As an Amor asteroid the orbit of 1998 QE2 is beyond Earth's orbit; the asteroid orbits the Sun at a distance of 1.0 -- 3.8 AU once 9 months. Its orbit has an inclination of 13 ° with respect to the ecliptic; the Earth minimum orbit intersection distance with the orbit of the asteroid is 0.035 AU, which translates into 13.4 lunar distances. As with many members of the Amor group, this asteroid has an aphelion beyond the orbit of Mars which makes it a Mars-crosser; the sooty surface of 1998 QE2 suggested that it might have been a comet that experienced a close encounter with the Sun.

However, the Tisserand parameter with respect to Jupiter does not make it obvious whether 1998 QE2 was a comet, since cometary TJ values are below 3. On May 31, 2013, 1998 QE2 approached within 0.039 AU of Earth at 20:59 UT. This was the closest approach, it is a strong radar target for Goldstone from May 30 to June 9 and will be one for Arecibo from June 6 to June 12. At its closest approach the asteroid had an apparent magnitude of 11 and therefore required a small telescope to be seen. Integrating the orbital solution shows the asteroid passed 0.08 AU from Earth on June 8, 1975, with an apparent magnitude of about 13.9. The next notable close approach will be May 27, 2221, when the asteroid will pass Earth at a distance of 0.038 AU. Goldstone radar observations on May 29, 2013 discovered that 1998 QE2 is orbited by a minor-planet moon 600–800 meters in diameter. In radar images, the satellite appears brighter than 1998 QE2 because it is rotating more which compresses the radar return of the satellite along the Doppler axis.

This makes the satellite appear narrow and bright compared to 1998 QE2. The satellite orbits the primary every 32 hours with a maximum separation of 6.4 kilometers. Once the satellite's orbit is well determined and astrophysicists will be able to determine the mass and density of 1998 QE2; the surface of 1998 QE2 is covered with a sooty substance, making it optically dark with a geometric albedo of 0.06, meaning it absorbs 94% of the light that hits it, indicative for a carbonaceous surface of a C-type asteroid. The asteroid is covered with craters and is dark and primitive. With a diameter between 2.7 and 3.2 kilometers, 1998 QE2 is one of largest known hazardous asteroid. Conversely, the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 1.08 kilometers based on an absolute magnitude of 17.2.
