ASTEROIDE / ¡ENTRE 110 Y 260 METROS DE DIÁMETRO!

La NASA advierte que un asteroide potencialmente peligroso se acercará a la Tierra el viernes 24, el cuerpo celeste tiene el tamaño de 'London Eye', la noria más alta de Reino Unido ...


Un masivo asteroide potencialmente peligroso pasará cerca de nuestro planeta este viernes, 24 de julio, según lo indican los datos del centro de la NASA para estudios de objetos cercanos a la Tierra (CNEOS, por sus siglas en inglés), que se encarga de monitorear diferentes aproximaciones a la Tierra de rocas espaciales.
Denominado '2020 ND', el cuerpo celeste tiene entre 110 y 260 metros en diámetro, superando en tamaño a la famosa noria londinense London Eye, la más alta de Reino Unido y de toda Europa, de 120 metros de diámetro.

La roca espacial —que se desplaza a una velocidad de casi 49.000 kilómetros por hora— se aproximará a nuestro planeta a una distancia mínima de 0,037 unidades astronómicas (5,5 millones de kilómetros), lo que permite clasificar al 2020 ND como 'potencialmente peligroso'.


La agencia espacial estadounidense define de esta forma a aquellos asteroides que pueden acercarse al planeta siguiendo una trayectoria que puede resultar amenazante, "en especial todos aquellos con una distancia mínima de intersección de órbita (MOID) de 0,05 unidades astronómicas o menos, y una magnitud absoluta (H) de 22,0 o menor".

Quando eu te falei em amor

Quando os meus olhos te tocaram
Eu senti que encontrara
A outra, metade de mim
Tive medo de acordar
Como se vivesse um sonho
Que não pensei em realizar
E a força do desejo
Faz me chegar perto de ti

Quando eu te falei em amor
Tu sorriste para mim
E o mundo ficou bem melhor
Quando eu te falei em amor
Nos sentimos os dois
Que o amanha vem depois
E não no fim

Estas linhas que hoje escrevo
São do livro da memória
Do que eu sinto por ti
E tudo o que tu me das
É parte da história que eu ainda não vivi
E a força do desejo
Faz me chegar de ti

Quando eu te falei em amor
Tu sorriste para mim
E o mundo ficou bem melhor
Quando eu te falei em amor
Nos sentimos os dois
Que o amanha vem depois e não no fim

Collide

The dawn is breaking
A light shining through
You're barely waking
And I'm tangled up in you
Yeah

But I'm open, you're closed
Where I follow, you'll go
I worry I won't see your face
Light up again

Even the best fall down sometimes
Even the wrong words seem to rhyme
Out of the doubt that fills my mind
I somehow find, you and I collide

I'm quiet, you know
You make a first impression
I've found I'm scared to know
I'm always on your mind

Even the best fall down sometimes
Even the stars refuse to shine
Out of the back you fall in time
I somehow find, you and I collide

Don't stop here
I've lost my place
I'm close behind

Even the best fall down sometimes
Even the wrong words seem to rhyme
Out of the doubt that fills your mind

You finally find, you and I collide
You finally find You and I collide
You finally findYou and I collide

Everything

You're a falling star, You're the get away
car.

You're the line in the sand when I go too
far.

You're the swimming pool, on an August day.
And You're the perfect thing to see.

And you play it coy, but it's kinda cute.
Ah, When you smile at me you know exactly what you
do.

Baby don't pretend, that you don't know it's
true.

Cause you can see it when I look at you.

And in this crazy life, and through these crazy
times

It's you, it's you, You make me sing.
You're every line, you're every word, you're
everything.


You're a carousel, you're a wishing well,
And you light me up, when you ring my bell.
You're a mystery, you're from outer space,
You're every minute of my everyday.

And I can't believe, uh that I'm your man,
And I get to kiss you baby just because I
can.

Whatever comes our way, ah we'll see it
through,

And you know that's what our love can do.

And in this crazy life, and through these crazy
times

It's you, it's you, You make me sing
You're every line, you're every word, you're
everything.


So, La, La, La, La, La, La, La
So, La, La, La, La, La, La, La

And in this crazy life, and through these crazy
times

It's you, it's you, You make me sing.
You're every line, you're every word, you're
everything.

You're every song, and I sing along.
Cause you're my everything.
yeah, yeah

So, La, La, La, La, La, La, La
So, La, La, La, La, La, La, La
