Я создал объект для запуска затмения, но не показываю значок затмения. Как я могу решить?

You need to add the Eclipse icon to the launcher you created, manually.
To do this, open the menu editor (shown in your second screenshot), right click on the "Eclipse" item you created, and select "Properties". This will give you a dialog box like this:
Click on the button with the spring / launcher icon, which will open a file chooser to pick an icon (image file). There's probably one included with the eclipse package / distribution you downloaded, if not, you can find one on Google images, save it, and use that.
