necesito que esta tarde todo vaya bien
para poder sacarte la manta de encima
y dejar que respires sin taquicardias.
para que tu única preocupación sea
saber cuáles son las app más molonas.

– has comido?
– no.
– te haré algo. mira,esta va a ser nuestra habitación.
– qué dices?

The Halley’s Comet

Halley’s Comet
or Comet Halley (officially designated 1P/Halley) is the most famous of the periodic comets and can currently be seen every 75–76 years. Many comets with long orbital During its returns to the inner solar system, it has been observed by astronomers since at least 240 BC, but it was not recognized as a periodic comet until the eighteenth century when its orbit was computed by English astronomer Edmond Halley, after whom the comet is now named. Halley’s Comet last appeared in the inner Solar System in 1986, and will next appear in mid-2061.
periods may appear brighter and more spectacular, but Halley is the only short-period comet that is clearly visible to the naked eye, and thus, the only naked-eye comet certain to return within a human lifetime.

The 1986 approach was the least favourable for Earth observers of all recorded passages of the comet throughout history: the comet did not achieve the spectacular brightness of some previous approaches, and with increased light pollution from urbanization, many people never saw the comet at all. Further, the comet appeared brightest when it was almost invisible from the northern hemisphere in March and April, prompting many amateur astronomers to travel to the southern hemisphere for a glimpse of the interloper. However, the development of space travel allowed scientists the opportunity to study the comet at close quarters, and several probes were launched to do so.
